Report of the President. ii 



dentally, too, in view of the thousands of acres in the interior of Long 

 Island now producing nothing but scrubby growths of pine, oak, and 

 chestnut, it is hoped to show that great opportunities here await the 

 farmer of small means. The information gathered concerns soils, 

 crops, methods, labor, harvesting, marketing, and the like. The de- 

 partment also worked in co-operation with the Department of Plant 

 Pathology on the investigation of the black-rot of grape and one bul- 

 letin on this important question has been published giving the results 

 of the experiments thus far, which show that the disease may be con- 

 trolled by the use of fungicides. Other investigations included an 

 inspection of peach yellow and little peach conducted during the 

 summer in the orchards of the Youngstown district, Niagara county, 

 while the studies commenced on the peony in co-operation with the 

 American Peony Association four years ago have been continued. 

 But perhaps the most important piece of work which this department 

 has in hand is the Cornell orchard survey, this movement combining 

 the features of a census and those of a biological study. Surveys of 

 six counties have now been completed, namely, Wayne, Orleans, 

 Niagara, Monroe, Ontario, and Orange, and it is proposed to extend 

 still further this exceedingly important line of horticultural exten- 

 sion effort. 



IX. Department of Entomology. The courses announced by this de- 

 partment had a total enrollment during the year of 378 students and 

 in addition to carrying on this work of instruction several members of 

 the staff have been engaged in the preparation of text-books for the 

 use of students and general readers, including a " Manual of the 

 Spiders of the United States," a book on " Insects Injurious to 

 Fruits," a work consisting of tables for the identification of the insects 

 of the northeastern United States, a text-book on " Insect Mor- 

 phology," and a text-book on " General Biology." Other research 

 work was concerned with insects and Crustacea that serve as the food 

 of fishes, and extensive studies of certain injurious insects, including 

 the habits and life history of the Timothy joint-worm and other 

 Isosomas infesting grains and grasses, with a view to devising a 

 method to prevent the injury caused by these insects, a study of the 

 apple-seed chalcis, grape-seed chalcis. and other seed-infesting chalcid- 

 flies, a study of a new leaf-miner of the plum, etc. The extension 

 work of this department consisted of an extensive correspondence 

 regarding injurious insects, a few co-operative experiments with 

 farmers in spraying, and attendance at fairs with exhibits of injurious 

 insects.
