Summary of English Sparrow Campaign on Campus in April 1914. Worthen shot 26 hrs. (2 hrs each morning for 13 days) and brought in 112 Eng. Sparrows, of which 63 were adult males, 45 adult ff, and 4 full-grown young. Worthen is paid 35c per hour; therefore killing of this number cost $9.10 plus cost of ammunition. Worthen with his helper (at 30c per hour) worked 26 hrs., and tore down 187 nests, which held 56 young and 41 eggs, costing $15.10. The entire April campaign cost $24.25 the funds being supplied by Mr. Martens. It appears, therefore, by far the cheaper method to shoot, just before the breeding season.
