rded for the best
houses made for the more common birds, such as wrens, bluebirds, and
martins. These should be judged as to adaptability or fitness to
purpose, amount of protection afforded to birds, good workmanship and
artistic merit. A prize might be awarded to the boy whose house has
the first pair of birds nesting in it. Prizes may be of many kinds,
but tools and books, as well as cash prizes are often given by local
business men.
