on the opposite
side of the outline, as compared with the first method. A box is then
nailed up and a clay or plaster-of-paris base made. This is oiled, and
the concrete put in place. In this case a wetter mixture than in the
first case should be used. The second templet is then used to strike
off the inside of the bowl. After this has set the pieces may be
assembled as before.

BIRD ENEMIES.

One sometimes wonders that birds manage to exist and to actually
increase in numbers. Possibly the first group of enemies should
include men and boys who kill adult birds, leaving the fledglings to
starve, or who rob the nests of eggs. It is the writer's belief that
every boy who makes one or more of the projects in this booklet, and
sees it occupied, will become one of a growing number who will care
for instead of destroy the birds of his neighborhood. Further, if
every man who now thoughtlessly or willfully destroys birds, knew the
real money value of the work birds do, he would build or buy houses
and food shelters to increase Nature's best friends to mankind.

The second group of enemies include ants and other vermin which at
times infest nests and nesting boxes, snakes, squirrels, mice and
rats. Protection against this group is afforded by bands of tin about
the pole, or spikes of wood or metal pointing downward so that access
is impossible by climbing up the pole. Another protection is to make
the entrance holes small enough to admit only the occupant for whom
the house was intended. Of course, the houses for the larger birds
must be protected in other ways. Charles Tesch of Milwaukee suggests a
sticky fly paper compound made of resin (melted) and castor oil as a
preventive for the inroads of the small red ant, if suitable support
is available.

The final group consists of the two worst foes of bird life, cats and
English or house sparrows. If you really value the birds that have
been reared in the house you have built you may need to get up _early_
more than one morning when the youngsters leave the nest to protect
them from the highly respectable (?) tabby that lives possibly next
door if not at your own house. It often comes to a choice between cats
and birds: and the cats may be disposed of in two ways--the right kind
of box traps for the homeless and unknown robbers, and an air rifle
with sufficient "sting" for the trespasser from next door. A few
lessons of this kind usually have some effect.
