nd. The only discovery of any moment was that made by
Dutchy's party, which found a small island separated from ours by a
narrow channel, through which the water ran like a mill-race. No spring
was discovered, so Uncle Ed had to construct his large filter. Bill and
I went over to Lumberville in search of a couple of cider barrels and a
pailful of charcoal. The barrels were placed one on top of the other
after cutting a large hole in the top of the lower barrel, and a smaller
one in the bottom of the upper one. The latter opening was covered by an
inverted saucer. Over this we spread a 3-inch layer of coarse sand, then
a 2-inch layer of charcoal, a 4-inch layer of clear, sharp sand, and a
2-inch top layer of gravel. The lower barrel was provided with a faucet,
through which we could draw off the filtered water as desired. In order
to keep the water cool we placed the filters in a shady place near the
river, and piled up earth around the lower barrel.

"Now, boys," said Uncle Ed, "form in line there, and we will go through
a fire drill."

He arranged us about five feet apart in a line extending from the filter
to the river. We had six pails, and these Dutchy filled one at a time,
passing them up the line to Reddy, who emptied them into the upper
barrel and then threw them back to Dutchy to be refilled. Working in
this way it did not take long to fill up the filter, and the burden of
keeping the barrels full, instead of falling on one person, was shared
alike by all.

THE KLEPALO.

Our camp outfit was further augmented by a dinner call. We discovered
the necessity of such a call on our very first day of camping. Dutchy
was so excited by his discoveries of the morning that he started out
alone in the afternoon to make a further search. The rest of us were
lazy after the noon meal, and were lolling around taking it easy during
the heat of the day, and discussing plans for the future. But Dutchy's
energetic nature would not permit him to keep quiet. He took the scow
and waded with it against the strong current to the deeper and quieter
water above the island. Then he rowed a long way up stream. He was gone
all the afternoon. Supper time came and still he didn't appear. The sun
was high, and I presume he didn't realize how late it was getting.
Finally, just at sunset, he came drifting down with the current, tired
and hungry, and ready for a large meal. But we had finished ou
