330 THE PLOVERS 



Harting examined the stomachs of many birds, and found that those from grass- 

 land on sandy soil had fed chiefly on beetles ; while in the stomachs of those from 

 downland where the soil was chalky, fragments of small snails, Helix virgata and 

 H. caperata, were found (Ibid., p. 238). Swallows particles of grit. The young are 

 attended by both parents, and assisted by them in their search for food, which 

 consists chiefly of insects and their larvae, small worms, spiders, and tiny 

 molluscs, [w. F.]
