THE MEADOW LARK is one of the most valuable birds that frequent farming regions. Throughout the year insects make up 73 per cent of its food, weed-seeds 12 per cent, and grain only 5 per cent. During the insect season, insects constitute 90 per cent of its food. THE BALTIMORE ORIOLE is as valuable to man as it is beautiful. Its nest is the most wonderful example of bird architecture in our land. In May insects constitute 90 per cent of this bird's food. For the entire year, insects and other animal food make 83.4 per cent and vegetable matter 16.6 per cent. THE CROW BLACKBIRD feeds as follows, throughout the whole year: insects, 26.9 per cent; other animal food 3.4; corn 37.2; oats, 2.9; wheat, 4.8; other grain, 1.6; fruits, 5; weed seeds and mast 18.2! This report was based on the examination (by the Biological Survey) of 2,346 stomachs, and "the charge that the blackbird is an habitual robber of birds' nests was disproved by the examinations." (F.E.L. Beal.) FLYCATCHERS.--The high-water mark in insect-destruction by our birds is reached by the flycatchers,--dull-colored, modest-mannered little creatures that do their work so quietly you hardly notice them. All you see in your tree-tops is a two-foot flit or glide, now here and now there, as the leaves and high branches are combed of their insect life. Bulletin No. 44 of the Department of Agriculture gives the residuum of an exhausting examination of 3,398 warbler stomachs, from seventeen species of birds, and the result is: 94.99 per cent of insect food,--mostly bad insects, too,--and 5.01 per cent vegetable food. What more can any forester ask of a bird?

Professor Beal has calculated the total quantity consumed in Iowa in one year,--in the days when sparrows were normally numerous,--at 1,750,000 pounds. THE AMERICAN GOLDFINCH as a weed destroyer has few equals. It makes a specialty of the seeds of the members of the Order Compositae, and is especially fond of the seeds of ragweed, thistles, wild lettuce and wild sunflower. But, small and beautiful as this bird is, there are hundreds of thousands of grown men in America who would shoot it and eat it if they dared! THE HAWKS AND OWLS.--Let no other state repeat the error that once was made in Pennsylvania when that state enacted in 1885, her now famous hawk-and-owl bounty law. In order to accomplish the wholesale destruction of her birds of prey, a law was passed providing for the payment of a bounty of fifty cents each for the scalps of hawks and owls. Immediately the slaughter began. In two years 180,000 scalps were brought in, and $90,000 were paid out for them. It was estimated that the saving to the farmers in poultry amounted to one dollar for each $1,205 paid out in bounties.
