<h5 id="id00139">THE FROZEN POND</h5>
<p id="id00140" style="margin-top: 2em">Daddy Blake hurried down cellar. Hal and Mab carefully putting away
their new skates, followed their father. Roly-Poly, the little fat
poodle dog looked around to see if he could find anything to drag
off and hide, but, seeing nothing, he went down cellar also, barking
loudly at each step.</p>
<p id="id00141">"Hal! Mab!" called Aunt Lolly. "Come back here, dears!"</p>
<p id="id00142">"We want to see what has happened!" answered Hal.</p>
<p id="id00143">"Oh, you'll get hurt! I'm sure you will!" exclaimed the dear, little,
fussy old lady aunt.</p>
<p id="id00144">"No, it isn't anything serious!" called Daddy Blake when he saw what
had happened. "Only one of the water pipes has burst. We must send for
the plumber. Wait, children, until I shut off the water, and then you
can come down. It is like a shower-bath now."</p>
<p id="id00145">Daddy Blake found the faucet, by which he could shut off the water at
the stationary wash-tubs, and then, when it had stopped spurting from
the burst pipe, he called to Hal and Mab:</p>
<p id="id00146">"Now you may come and see how strong ice is. Not only does it burst
glass bottles, but it will even crack an iron pipe."</p>
<p id="id00147">"Just like it cracked a cannon ball!" cried Hal, and he was in such a
hurry to get down the cellar steps that he jumped two at a time.</p>
<p id="id00148">That might have been all right, only Roly-Poly, the little fat poodle
dog, did the same thing. He became tangled up in Hal's legs, and,
a moment later, the little boy and the dog were rolling toward the
bottom of the steps, over and over just like a pumpkin.</p>
<p id="id00149">"Oh!" cried Mab, holding fast to the handrail, a little frightened.</p>
<p id="id00150">"Oh my!" exclaimed Mamma Blake at the top of the cellar steps. "What
has happened?"</p>
<p id="id00151">"Oh my goodness me sakes alive and some orange pudding!" exclaimed<br/>
Aunt Lolly. "I just knew <i>something</i> would happen!"<br/></p>
<p id="id00152">But nothing much did, after all, for Daddy Blake, as soon as he heard
Hal falling, ran to the foot of the stairs, and there he caught his
little boy before Hal had bounced down many steps.</p>
<p id="id00153">"There you are!" cried Daddy Blake, as he set Hal upright on his feet.<br/>
"Not hurt a bit; are you?"<br/></p>
<p id="id00154">"N-n-n-n-no!" stammered Hal, as he caught his breath, which had almost
gotten away from him. "I'm not hurt. Is Roly-Poly?"</p>
<p id="id00155">Roly was whirling about, barking and trying to catch his tail, so I
guess he was not much hurt. The truth was that both Hal and Roly were
so fat and plump, that falling down a few cellar steps did not hurt
them in the least.</p>
<p id="id00156">"Well, now we'll look at the burst water pipe," said Daddy Blake,
when the excitement was over. The water had stopped spurting out now,
though there was quite a puddle of it on the cellar floor by the tubs.</p>
<p id="id00157">Mr. Blake lifted Hal across this, and showed him where there was a big
crack in the water pipe. Then he showed Mab, also lifting her across
the little pond in the cellar.</p>
<p id="id00158">"You see the pipe was full of water," Mr. Blake explained, "and in the
night it got so cold down cellar that the water froze, just as it did
in the glass bottle out on the back porch.</p>
<p id="id00159">"Then the ice swelled up, and it was so strong that it burst the
strong iron pipe, splitting it right down the side."</p>
<p id="id00160">"But why didn't the water spurt out when I came down cellar earlier
this morning?" asked Mamma Blake. "It did not leak then."</p>
<p id="id00161">"I suppose it was still frozen," answered her husband. "But when the
furnace fire became hotter it melted the ice in the pipe and that let
the water spurt out. But the plumber will soon fix it."</p>
<p id="id00162">Hal and Mab watched the plumber, to whom their papa telephoned. He had
to take out the broken pipe, and put in a new piece. Afterward Hal
looked at the pipe that had been split by the ice.</p>
<p id="id00163">"Why it's just as if gun-powder blew it up," he said, for once he had
seen a toy cannon that had burst on Fourth of July, from having too
much powder in it.</p>
<p id="id00164">"Yes, freezing ice is just as strong as gunpowder, only it works more
slowly," said Daddy Blake with a smile. "Powder goes off with a puff,
a flash and a roar, but ice freezes slowly."</p>
<p id="id00165">"Oh, but when are we going skating?" asked Mab, as she and her brother
started for school, a little later that morning.</p>
<p id="id00166">"As soon as I can find a frozen pond," said Daddy Blake with a smile.</p>
<p id="id00167">Well wrapped up, and wearing warm gloves, Hal and Mab went to their
lessons. It was so cold that wintry day, though there was no snow,
that they ran instead of walking. Running made them warm.</p>
<p id="id00168">"Is my nose red?" asked Mab, when they were near the school.</p>
<p id="id00169">"Oh, it's awful red!" cried Hal. "Is mine?"</p>
<p id="id00170">"As red as a boiled lobster!" laughed Mab. "Let's run faster!"</p>
<p id="id00171">So they ran, and soon they were in a glow of warmth.</p>
<p id="id00172">"Oh!" cried Mab, as she and her brother entered the school-yard, "we
forgot to ask Daddy why we get warm when we run."</p>
<p id="id00173">When the two children reached their house, after lessons were over for
the day, they found their father waiting for them. He had his skates
over his shoulder, dangling from a strap, and he had Hal's and Mab's
in his hand.</p>
<p id="id00174">"Come, we are going to look for the frozen pond!" he said.</p>
<p id="id00175">Then Hal and Mab forgot all about asking why they became warm when
they ran. They cried out joyfully:</p>
<p id="id00176">"Oh, Daddy is going to take us skating! Daddy is going to take us
skating!"</p>
<p id="id00177">Across the fields they went, and in a little while they came to a
place where was a pond, in which they used to fish during the summer.
But now as they looked down on the water, from the top of a small
hill, they saw that the pond was all frozen over. A sheet of ice
covered it from edge to edge.</p>
<p id="id00178">"Oh, now we can skate!" cried Hal in delight, "Now we can try our new
skates."</p>
