Pursuant to certain complaints of serious injury by wood-boring insects to girdled cypress timber in the South Atlantic and Gulf States, the Bureau of Entomology began a series of experiments and investigations with special trees girdled on definite dates in every month of the year, as well as with those girdled in regular operations at known dates or periods, to determine whether or not there was any important relation between the month or time of year the trees were girdled and subsequent injuries. This work was personally conducted by specialists of the Bureau in cooperation with cypress manufacturers in southeastern North Carolina, southern South Carolina, southeastern Georgia, western Florida, and southern Louisiana. It was begun in the spring of 1903 and continued until December, 1904.
