fairly accurate grade can be made.

The tile pipes were laid upon a bed of gravel. This prevents the
clogging up of the loosely put together joints. To fit tiles place the
small end of one into the large end of the next, and so on. Over the end
of the last tile, which emptied into the brook, they wired a bit of
rather fine-meshed chicken wire.

Then the trench was filled in. By test Albert had found the soil of this
land acid. Lime was to be put on it. Now lime must be in a crumbling
state for this purpose. So after they had bought the lime they dumped it
in a heap on a corner of the plot. After it had become air slaked, or
reduced to a powder by the action of air upon it, it was spread over the
lot. This and considerable fertilizer was ploughed in. The boys then had
an ideal sort of planting soil for almost anything. The drain actually
worked.

Now some boy may ask, suppose a fellow has no tile and cannot afford to
buy any. In such a case there are two alternatives or choices. A wooden
trough may be made by nailing together boards six inches wide. Then make
a gravel bed and tip this trough over on it peak up. The wooden drain,
however, is likely to rot. The other way is to put a double row of
stones right through the centre of the bed slope. These
stones--perfectly flat ones--should be placed on end with a foot between
the rows. In this space put small stones.

The chief thing to remember in the drainage problem is that one wants a
gradual flow of water from inlet to outlet. Any boy can fix his wet,
soggy garden spot even though he has no tiles. Stones can be found
surely, and, if no gravel beds are near, all the little brothers and
