If corn can be protected by tarring, so that the crows will not eat it, they will prove a benefit by leaving the corn and picking up grubs in the field. Where corn has been tarred, I have never known the crows to touch it. Mr. Sedgwick remarked that, in addition to destroying the corn crop, the crow was also very destructive of the eggs of other birds. Last spring I watched a pair of crows flying through an orchard, and in several instances saw them fly into birds' nests, take out the eggs, and then go on around the field. In answer to Mr. Hubbard, who claimed the crow would eat animal food in any form, and might not be rightly classified as a grain-eating bird, Prof. Stearns said the crow was thus classified by reason of the structure of its crop being similar to that of the finches, the blackbird, the sparrows, and other seed-eating birds. [Illustration: THE AMERICAN CROW.] Mr. Wetherell said: Crows are greedy devourers of the white worm, which sometimes destroys acres of grass. As a grub eater, the crow deserves much praise. The crow is the scavenger of the bird family, eating anything and everything, whether it is sweet or carrion. The only quarrel I have with the crow is because it destroys the eggs and young birds. Mr. Lockwood described the experience of a neighbor who planted corn after tarring it. This seemed to prevent the ravages of the crows until the second hoeing, when the corn was up some eighteen inches, at which time the crows came in and pulled nearly an acre clean. Crows, said Dr. Riggs, have no crop, like a great many carnivorous birds. The passage leading from the mouth goes directly to the gizzard, something like the duck. The duck has no crop, yet the passage leading from the mouth to the gizzard in the duck becomes considerably enlarged. In the crow there is no enlargement of this passage, and everything passes directly into the gizzard, where it is digested. Dr. Riggs had raised corn and watched the operations of the crows. Going upon the field in less than a minute after the crows had left it, he found they had pulled the corn, hill after hill, marching from one hill to the other. Not until the corn had become softened and had come up would they molest it. In the fall they would come in droves on to a field of corn, where it is in stacks, pick out the corn from the husks, and put it into their gizzards. They raid robbins' nests and swallows' nests, devouring eggs and young birds. Yet crows are great scavengers. In the spring they get a great many insects and moths from the ground, and do good work in picking up those large white grubs with red heads that work such destruction in some of our mowing fields.
