blooming late in June and continued until October, attaining a height of from five to six feet. Three related species were also under observa. tion for hybridizing, "Golden Bowl" (Hibiscus Manihot), "Roselle" (Hibiscus Sabdariffa) and Hibiscus Africanus, the last being a horticultural species nearly related to the familiar weed "Flower of an Hour" (Hibis cus Trionum.)

Attempts made to hybridize the "Marsh Mallow" (Hibiscus Moscheutos) with the hybrid and with the "Althea" (Hibiscus Syriacus) were unsuc cessful.

GENERAL OUTLINE OF WORK.

The attention of the entomologist has been devoted this year to furnishing information and other assistance, insofar as his means would permit, as the need arose. He has also carried forward investigations of anti-peach-borer coatings, of the effect of various sprays and dusts on potato foliage and yield, and of the problems of house fly and mosquito control.

The present year has seen a considerable amount of change in the staff. Miss Augusta E. Meske has continued her efficient management of the clerical affairs of the office. Mr. C. H. Richardson, Jr., took up and carried on the work against the house fly and its allies. On April 1st Mr. A. E. Cameron, who holds a scholarship of the Board of Agriculture of England, joined the force for the purpose of gaining practical experience in field methods of insect control.
