<p>I learned arithmetic in Scotland without understanding any of it,
though I had the rules by heart. But when I was about fifteen or
sixteen years of age, I began to grow hungry for real knowledge, and
persuaded father, who was willing enough to have me study provided my
farm work was kept up, to buy me a higher arithmetic. Beginning at the
beginning, in one summer I easily finished it without assistance, in
the short intervals between the end of dinner and the afternoon start
for the harvest-and hay-fields, accomplishing more without a teacher
in a few scraps of time than in years in school before my mind was
ready for such work. Then in succession I <span class="pagenum"><SPAN name="Page_241" id="Page_241"></SPAN></span>took up algebra, geometry,
and trigonometry and made some little progress in each, and reviewed
grammar. I was fond of reading, but father had brought only a few
religious books from Scotland. Fortunately, several of our neighbors
had brought a dozen or two of all sorts of books, which I borrowed and
read, keeping all of them except the religious ones carefully hidden
from father's eye. Among these were Scott's novels, which, like all
other novels, were strictly forbidden, but devoured with glorious
pleasure in secret. Father was easily persuaded to buy Josephus' "Wars
of the Jews," and D'Aubigné's "History of the Reformation," and I
tried hard to get him to buy Plutarch's Lives, which, as I told him,
everybody, even religious people, praised as a grand good book; but he
would have nothing to do with the old pagan until the graham bread and
anti-flesh doctrines came suddenly into our backwoods neighborhood,
making a stir something like phrenology and spirit-rappings, which
were as mysterious in their <span class="pagenum"><SPAN name="Page_242" id="Page_242"></SPAN></span>attacks as influenza. He then thought it
possible that Plutarch might be turned to account on the food question
by revealing what those old Greeks and Romans ate to make them strong;
and so at last we gained our glorious Plutarch. Dick's "Christian
Philosopher," which I borrowed from a neighbor, I thought I might
venture to read in the open, trusting that the word "Christian" would
be proof against its cautious condemnation. But father balked at the
word "Philosopher," and quoted from the Bible a verse which spoke of
"philosophy falsely so-called." I then ventured to speak in defense of
the book, arguing that we could not do without at least a little of
the most useful kinds of philosophy.</p>
<p>"Yes, we can," he said with enthusiasm, "the Bible is the only book
human beings can possibly require throughout all the journey from
earth to heaven."</p>
<p>"But how," I contended, "can we find the way to heaven without the
Bible, and how after we grow old can we read the Bible <span class="pagenum"><SPAN name="Page_243" id="Page_243"></SPAN></span>without a
little helpful science? Just think, father, you cannot read your Bible
without spectacles, and millions of others are in the same fix; and
spectacles cannot be made without some knowledge of the science of
optics."</p>
<p>"Oh!" he replied, perceiving the drift of the argument, "there will
always be plenty of worldly people to make spectacles."</p>
<p>To this I stubbornly replied with a quotation from the Bible with
reference to the time coming when "all shall know the Lord from the
least even to the greatest," and then who will make the spectacles?
But he still objected to my reading that book, called me a
contumacious quibbler too fond of disputation, and ordered me to
return it to the accommodating owner. I managed, however, to read it
later.</p>
<p>On the food question father insisted that those who argued for a
vegetable diet were in the right, because our teeth showed plainly
that they were made with reference to fruit and grain and not for
flesh like those of dogs and wolves and tigers. He therefore promptly
<span class="pagenum"><SPAN name="Page_244" id="Page_244"></SPAN></span>adopted a vegetable diet and requested mother to make the bread from
graham flour instead of bolted flour. Mother put both kinds on the
table, and meat also, to let all the family take their choice, and
while father was insisting on the foolishness of eating flesh, I came
to her help by calling father's attention to the passage in the Bible
which told the story of Elijah the prophet who, when he was pursued by
enemies who wanted to take his life, was hidden by the Lord by the
brook Cherith, and fed by ravens; and surely the Lord knew what was
good to eat, whether bread or meat. And on what, I asked, did the Lord
feed Elijah? On vegetables or graham bread? No, he directed the ravens
to feed his prophet on flesh. The Bible being the sole rule, father at
once acknowledged that he was mistaken. The Lord never would have sent
flesh to Elijah by the ravens if graham bread were better.</p>
<p>I remember as a great and sudden discovery that the poetry of the
Bible, Shakespeare, and Milton was a source of inspiring,
exhilarating, <span class="pagenum"><SPAN name="Page_245" id="Page_245"></SPAN></span>uplifting pleasure; and I became anxious to know all
the poets, and saved up small sums to buy as many of their books as
possible. Within three or four years I was the proud possessor of
parts of Shakespeare's, Milton's, Cowper's, Henry Kirke White's,
Campbell's, and Akenside's works, and quite a number of others seldom
read nowadays. I think it was in my fifteenth year that I began to
relish good literature with enthusiasm, and smack my lips over
favorite lines, but there was desperately little time for reading,
even in the winter evenings,—only a few stolen minutes now and then.
Father's strict rule was, straight to bed immediately after family
worship, which in winter was usually over by eight o'clock. I was in
the habit of lingering in the kitchen with a book and candle after the
rest of the family had retired, and considered myself fortunate if I
got five minutes' reading before father noticed the light and ordered
me to bed; an order that of course I immediately obeyed. But night
after night I tried to steal minutes in the same <span class="pagenum"><SPAN name="Page_246" id="Page_246"></SPAN></span>lingering way, and
how keenly precious those minutes were, few nowadays can know. Father
failed perhaps two or three times in a whole winter to notice my light
for nearly ten minutes, magnificent golden blocks of time, long to be
remembered like holidays or geological periods. One evening when I was
reading Church history father was particularly irritable, and called
out with hope-killing emphasis, "<i>John go to bed!</i> Must I give you a
separate order every night to get you to go to bed? Now, I will have
no irregularity in the family; you <i>must</i> go when the rest go, and
without my having to tell you." Then, as an afterthought, as if
judging that his words and tone of voice were too severe for so
pardonable an offense as reading a religious book he unwarily added:
"If you <i>will</i> read, get up in the morning and read. You may get up in
the morning as early as you like."</p>
<p>That night I went to bed wishing with all my heart and soul that
somebody or something might call me out of sleep to avail myself of
<span class="pagenum"><SPAN name="Page_247" id="Page_247"></SPAN></span>this wonderful indulgence; and next morning to my joyful surprise I
awoke before father called me. A boy sleeps soundly after working all
day in the snowy woods, but that frosty morning I sprang out of bed as
if called by a trumpet blast, rushed downstairs, scarce feeling my
chilblains, enormously eager to see how much time I had won; and when
I held up my candle to a little clock that stood on a bracket in the
kitchen I found that it was only one o'clock. I had gained five hours,
almost half a day "Five hours to myself!" I said, "five huge, solid
hours!" I can hardly think of any other event in my life, any
discovery I ever made that gave birth to joy so transportingly
glorious as the possession of these five frosty hours.</p>
<p>In the glad, tumultuous excitement of so much suddenly acquired
time-wealth, I hardly knew what to do with it. I first thought of
going on with my reading, but the zero weather would make a fire
necessary, and it occurred to me that father might object to the cost
of <span class="pagenum"><SPAN name="Page_248" id="Page_248"></SPAN></span>firewood that took time to chop. Therefore, I prudently decided to
go down cellar, and begin work on a model of a self-setting sawmill I
had invented. Next morning I managed to get up at the same gloriously
early hour, and though the temperature of the cellar was a little
below the freezing point, and my light was only a tallow candle the
mill work went joyfully on. There were a few tools in a corner of the
cellar,—a vise, files, a hammer, chisels, etc., that father had
brought from Scotland, but no saw excepting a coarse crooked one that
was unfit for sawing dry hickory or oak. So I made a fine-tooth saw
suitable for my work out of a strip of steel that had formed part of
an old-fashioned corset, that cut the hardest wood smoothly. I also
made my own bradawls, punches, and a pair of compasses, out of wire
and old files.</p>
<p>My workshop was immediately under father's bed, and the filing and
tapping in making cogwheels, journals, cams, etc., must, no doubt,
have annoyed him, but with the permission he <span class="pagenum"><SPAN name="Page_249" id="Page_249"></SPAN></span>had granted in his mind,
and doubtless hoping that I would soon tire of getting up at one
o'clock, he impatiently waited about two weeks before saying a word. I
did not vary more than five minutes from one o'clock all winter, nor
did I feel any bad effects whatever, nor did I think at all about the
subject as to whether so little sleep might be in any way injurious;
it was a grand triumph of will-power over cold and common comfort and
work-weariness in abruptly cutting down my ten hours' allowance of
sleep to five. I simply felt that I was rich beyond anything I could
have dreamed of or hoped for. I was far more than happy. Like Tam o'
Shanter I was glorious, "O'er a' the ills o' life victorious."</p>
<p>Father, as was customary in Scotland, gave thanks and asked a blessing
before meals, not merely as a matter of form and decent Christian
manners, for he regarded food as a gift derived directly from the
hands of the Father in heaven. Therefore every meal to him was a
sacrament requiring conduct and attitude of mind not <span class="pagenum"><SPAN name="Page_250" id="Page_250"></SPAN></span>unlike that
befitting the Lord's Supper. No idle word was allowed to be spoken at
our table, much less any laughing or fun or story-telling. When we
were at the breakfast-table, about two weeks after the great golden
time-discovery, father cleared his throat preliminary, as we all knew,
to saying something considered important. I feared that it was to be
on the subject of my early rising, and dreaded the withdrawal of the
permission he had granted on account of the noise I made, but still
hoping that, as he had given his word that I might get up as early as
I wished, he would as a Scotchman stand to it, even though it was
given in an unguarded moment and taken in a sense unreasonably
far-reaching. The solemn sacramental silence was broken by the dreaded
question:—</p>
<p>"John, what time is it when you get up in the morning?"</p>
<p>"About one o'clock," I replied in a low, meek, guilty tone of voice.</p>
<p>"And what kind of a time is that, getting up <span class="pagenum"><SPAN name="Page_251" id="Page_251"></SPAN></span>in the middle of the
night and disturbing the whole family?"</p>
<p>I simply reminded him of the permission he had freely granted me to
get up as early as I wished.</p>
<p>"I <i>know</i> it," he said, in an almost agonized tone of voice, "I <i>know</i>
I gave you that miserable permission, but I never imagined that you
would get up in the middle of the night."</p>
<p>To this I cautiously made no reply, but continued to listen for the
heavenly one-o'clock call, and it never failed.</p>
<p>After completing my self-setting sawmill I dammed one of the streams in
the meadow and put the mill in operation. This invention was speedily
followed by a lot of others,—water-wheels, curious doorlocks and
latches, thermometers, hygrometers, pyrometers, clocks, a barometer, an
automatic contrivance for feeding the horses at any required hour, a
lamp-lighter and fire-lighter, an early-or-late-rising machine, and so
forth.</p>
<p>After the sawmill was proved and discharged <span class="pagenum"><SPAN name="Page_252" id="Page_252"></SPAN></span>from my mind, I happened
to think it would be a fine thing to make a timekeeper which would
tell the day of the week and the day of the month, as well as strike
like a common clock and point out the hours; also to have an
attachment whereby it could be connected with a bedstead to set me on
my feet at any hour in the morning; also to start fires, light lamps,
etc. I had learned the time laws of the pendulum from a book, but with
this exception I knew nothing of timekeepers, for I had never seen the
inside of any sort of clock or watch. After long brooding, the novel
clock was at length completed in my mind, and was tried and found to
be durable and to work well and look well before I had begun to build
it in wood. I carried small parts of it in my pocket to whittle at
when I was out at work on the farm, using every spare or stolen moment
within reach without father's knowing anything about it. In the middle
of summer, when harvesting was in progress, the novel time-machine was
nearly completed. It was hidden upstairs in a <span class="pagenum"><SPAN name="Page_253" id="Page_253"></SPAN></span>spare bedroom where
some tools were kept. I did the making and mending on the farm, but
one day at noon, when I happened to be away, father went upstairs for
a hammer or something and discovered the mysterious machine back of
the bedstead. My sister Margaret saw him on his knees examining it,
and at the first opportunity whispered in my ear, "John, fayther saw
that thing you're making upstairs." None of the family knew what I was
doing, but they knew very well that all such work was frowned on by
father, and kindly warned me of any danger that threatened my plans.
The fine invention seemed doomed to destruction before its
time-ticking commenced, though I thought it handsome, had so long
carried it in my mind, and like the nest of Burns's wee mousie it had
cost me mony a weary whittling nibble. When we were at dinner several
days after the sad discovery, father began to clear his throat to
speak, and I feared the doom of martyrdom was about to be pronounced
on my grand clock.</p>
<p><span class="pagenum"><SPAN name="Page_254" id="Page_254"></SPAN></span>"John," he inquired, "what is that thing you are making upstairs?"</p>
<p>I replied in desperation that I didn't know what to call it.</p>
<p>"What! You mean to say you don't know what you are trying to do?"</p>
<p>"Oh, yes," I said, "I know very well what I am doing."</p>
<p>"What, then, is the thing for?"</p>
<p>"It's for a lot of things," I replied, "but getting people up early in
the morning is one of the main things it is intended for; therefore it
might perhaps be called an early-rising machine."</p>
<p>After getting up so extravagantly early, all the last memorable winter
to make a machine for getting up perhaps still earlier seemed so
ridiculous that he very nearly laughed. But after controlling himself
and getting command of a sufficiently solemn face and voice he said
severely, "Do you not think it is very wrong to waste your time on
such nonsense?"</p>
<p>"No," I said meekly, "I don't think I'm doing any wrong."</p>
<p><span class="pagenum"><SPAN name="Page_255" id="Page_255"></SPAN></span>"Well," he replied, "I assure you I do; and if you were only half as
zealous in the study of religion as you are in contriving and
whittling these useless, nonsensical things, it would be infinitely
better for you. I want you to be like Paul, who said that he desired
to know nothing among men but Christ and Him crucified."</p>
<p>To this I made no reply, gloomily believing my fine machine was to be
burned, but still taking what comfort I could in realizing that anyhow
I had enjoyed inventing and making it.</p>
<p>After a few days, finding that nothing more was to be said, and that
father after all had not had the heart to destroy it, all necessity
for secrecy being ended, I finished it in the half-hours that we had
at noon and set it in the parlor between two chairs, hung moraine
boulders that had come from the direction of Lake Superior on it for
weights, and set it running. We were then hauling grain into the barn.
Father at this period devoted himself entirely to the Bible and did no
farm work <span class="pagenum"><SPAN name="Page_256" id="Page_256"></SPAN></span>whatever. The clock had a good loud tick, and when he heard
it strike, one of my sisters told me that he left his study, went to
the parlor, got down on his knees and carefully examined the
machinery, which was all in plain sight, not being enclosed in a case.
This he did repeatedly, and evidently seemed a little proud of my
ability to invent and whittle such a thing, though careful to give no
encouragement for anything more of the kind in future.</p>
<p>But somehow it seemed impossible to stop. Inventing and whittling
faster than ever, I made another hickory clock, shaped like a scythe
to symbolize the scythe of Father Time. The pendulum is a bunch of
arrows symbolizing the flight of time. It hangs on a leafless mossy
oak snag showing the effect of time, and on the snath is written, "All
flesh is grass." This, especially the inscription, rather pleased
father, and, of course, mother and all my sisters and brothers admired
it. Like the first it indicates the days of the week and month, starts
fires and beds at any given hour and minute, and, <span class="pagenum"><SPAN name="Page_257" id="Page_257"></SPAN></span>though made more
than fifty years ago, is still a good timekeeper.</p>
<p>My mind still running on clocks, I invented a big one like a town
clock with four dials, with the time-figures so large they could be
read by all our immediate neighbors as well as ourselves when at work
in the fields, and on the side next the house the days of the week and
month were indicated. It was to be placed on the peak of the barn
roof. But just as it was all but finished, father stopped me, saying
that it would bring too many people around the barn. I then asked
permission to put it on the top of a black-oak tree near the house.
Studying the larger main branches, I thought I could secure a
sufficiently rigid foundation for it, while the trimmed sprays and
leaves would conceal the angles of the cabin required to shelter the
works from the weather, and the two-second pendulum, fourteen feet
long, could be snugly encased on the side of the trunk. Nothing about
the grand, useful timekeeper, I argued, would disfigure the tree, for
it would look something like <span class="pagenum"><SPAN name="Page_258" id="Page_258"></SPAN></span>a big hawk's nest. "But that," he
objected, "would draw still bigger bothersome trampling crowds about
the place, for who ever heard of anything so queer as a big clock on
the top of a tree?" So I had to lay aside its big wheels and cams and
rest content with the pleasure of inventing it, and looking at it in
my mind and listening to the deep solemn throbbing of its long
two-second pendulum with its two old axes back to back for the bob.</p>
<p>One of my inventions was a large thermometer made of an iron rod,
about three feet long and five eighths of an inch in diameter, that
had formed part of a wagon-box. The expansion and contraction of this
rod was multiplied by a series of levers made of strips of hoop iron.
The pressure of the rod against the levers was kept constant by a
small counterweight, so that the slightest change in the length of the
rod was instantly shown on a dial about three feet wide multiplied
about thirty-two thousand times. The zero-point was gained by packing
the rod in wet snow. The scale was so large <span class="pagenum"><SPAN name="Page_259" id="Page_259"></SPAN></span>that the big black hand
on the white-painted dial could be seen distinctly and the temperature
read while we were ploughing in the field below the house. The
extremes of heat and cold caused the hand to make several revolutions.
The number of these revolutions was indicated on a small dial marked
on the larger one. This thermometer was fastened on the side of the
house, and was so sensitive that when any one approached it within
four or five feet the heat radiated from the observer's body caused
the hand of the dial to move so fast that the motion was plainly
visible, and when he stepped back, the hand moved slowly back to its
normal position. It was regarded as a great wonder by the neighbors
and even by my own all-Bible father.</p>

<p>Boys are fond of the books of travelers, and I remember that one day,
after I had been reading Mungo Park's travels in Africa, mother said:
"Weel, John, maybe you will travel like Park and Humboldt some day."
Father overheard her and cried out in solemn deprecation, <span class="pagenum"><SPAN name="Page_260" id="Page_260"></SPAN></span>"Oh, Anne!
dinna put sic notions in the laddie's heed." But at this time there
was precious little need of such prayers. My brothers left the farm
when they came of age, but I stayed a year longer, loath to leave
home. Mother hoped I might be a minister some day; my sisters that I
would be a great inventor. I often thought I should like to be a
physician, but I saw no way of making money and getting the necessary
education, excepting as an inventor. So, as a beginning, I decided to
try to get into a big shop or factory and live a while among machines.
But I was naturally extremely shy and had been taught to have a poor
opinion of myself, as of no account, though all our neighbors
encouragingly called me a genius, sure to rise in the world. When I
was talking over plans one day with a friendly neighbor, he said:
"Now, John, if you wish to get into a machine-shop, just take some of
your inventions to the State Fair, and you may be sure that as soon as
they are seen they will open the door of any shop in the country for
you. You will be <span class="pagenum"><SPAN name="Page_261" id="Page_261"></SPAN></span>welcomed everywhere." And when I doubtingly asked if
people would care to look at things made of wood, he said, "Made of
wood! Made of wood! What does it matter what they're made of when they
are so out-and-out original. There's nothing else like them in the
world. That is what will attract attention, and besides they're mighty
handsome things anyway to come from the backwoods." So I was
encouraged to leave home and go at his direction to the State Fair
when it was being held in Madison.</p>
