34 pp. Pamphlet bound in hardcover boards with original wrappers preserved. "As a result of investigations during the years 1906 and 1907, our knowledge of the part birds play in restricting the ravages of the pest was considerably increased, and a number of additional species were founds to feed upon the weevil. Practical suggestions are made in the bulletin for increasing the number of swallows breeding in the cotton districts, swallows having been ascertained to be among the most important enemies of the pest."
