 The Killdeer 223 cotton -growing districts. It is also especially effective in holding in check the Rocky Mountain locust, having received special mention in the government report on that destructive insect. . In Bulletin No. 25, United States Department of Agriculture, the government expert, Arthur H. Howell, says: "The Killdeer frequents plowed fields, often in large numbers, and the destruction of weevils at the period of spring plowing is a highly important service." We find that the Killdeer is of great value aesthetically by reason of its beauty and interesting personality; it is of extreme value economically because it destroys enormous numbers of insects, two kinds of which are costing the agriculturists of the country millions of dollars annually; it is practically worthless for food owing to its small size, and no self-respecting sportsman ever shoots one. Let me quote from a quaint old volume published in 1848 by that prince of sportsmen, Frank Forester, who, at the end of his chapter on the Plovers, adds these few words: "In addition to these we have the well-known, common and beautiful variety, the Killdeer Plover, so named from its peculiar cry, which it is both cruel and useless to kill, as it is too insignificant to be regarded as game." Let the public give the Killdeer the appreciation and protection it richly deserves. Questions for Teachers and Students How are feet of Plover different from those of other birds?
