The protection of crops and poultry from bird depre- dations.

If, with little trouble and expense, he can make his farmstead attractive to the more valuable species, he may be able to lure to it and maintain on it, more birds than it would ordinarily support,—particularly if he is willing to provide them with a little inexpensive food to tide them over hard places. In this way, he may secure on his own land the full benefit of the ser- vices of birds as insect- and weed-destroyers. Food is the magnet which will attract all spe- cies.
