The experimental work in these fields covers a variety of cultural problems N, and is most extensively developed in the breeding of improved fruits and vegetables, li 3 including potatoes, especially adapted to Minnesota conditions. The instruction given Q on the campus is offered to four rather distinct groups,-students in the Graduate 4 . . . , xx' School of the University, undergraduate students in the College' of Agriculture, For- iafx estry and Home Economics, students in the School of Agriculture, and Short Course l' u n s 1 I u n Xl students. In addition to the week's program of horticultural instruction given during 1 Y Farmers' and Home-Makers' Week, a short course for commercial florists and another in by general horticulture are offered. In the extension field a wide correspondence is main- ' ll ' ' u A 4 u 1 tained and in the absence of a regular extension specialist in horticulture all members N A . . . - . . . g of the staff cooperate in attending meetings and demonstrations in various parts of the y state.

The Division of Soils ' 1 VERY farmer wishes to know just what treatment the soil of his farm needs in fx, i order that he may secure the largest yields that can be produced at a profit. Nearly f. every farm in Minnesota has two or more different types of soil and these often X4 need different methods of fertilization, cultivation and cropping if they are to give ,QNX the highest possible returns. Xi The soils course in the school deals with the formation and properties of soils Q ! in general but especial attention is given to the study of Minnesota soils and the means mi for maintaining or improving their productivity. The growing of legumes for the purpose of restoring and maintaining the nitrogen content of the soil is advocated. The if, student is also taught how to test the soil as to its acid alkaline reaction and learns the value of chemical analyses. Much of the time of the Staff of the Division of Soils is given to experiments with different fertilizers and different forms of lime on various soil types in widely scattered localities in the state. During the summer two members of the staff, assisted by college QC graduates and undergraduates, are engaged on the soil survey of different counties. Home projects in soils are offered to the school students. The most popular are those that have to do with the Various forms of commercial fertilizers. Many of the sludlents hive obtagxied very slirilling resilts wllnich have led to the use of fertilizers on N t e ome arm an ater on t e arms o neig ors. ,gy M-- s . 4 -- -z , -zz . .

Y 4' 5 i The Division of Entomology and Economic Zoology f 4 6 l MONG the many important problems taking the time of the members of the A Division of Entomology and Economic Zoology is the one concerning the Q44 control of injurious insects. The insects for the most part do their damage x . . . . ' before they are recognized as dangerous and it is only by keeping constantly on guard that the grower can combat these insidious pests. One of the principal methods of N Q6 combating injurious insects is by the use of insecticides such as paris green, arsenate of lil. lead, nicotine, oil or soap. To kill a chewing insect an internal or stomach poison is required. The principal ingredient in the most of these stomach poisons is arsenic. When used in a spray the 3 is particles of poison are held in suspension in the liquid and settle down on the leaf when the Water evaporates. Much experimental work is required to determine the value of an aj insecticide. The sticky quality is one of the valuable assets of a stomach insecticide. ' 131 . . . lx MQ In the picture Professor A. L. Strand has just demonstrated the electrical charge present on the particles in a brand of arsenate of lead. It has been proven that where the spray has a charge different from the leaf to be sprayed, the poison will stick better. As the leaf usually has a negative charge it is necessary for best results to have a poison fl-. W' - . . , . Mxlq with a positive charge. At the present time several manufacturers of stomach poisons X-Y . . . Eg sul are trying to do this for their products. iflffv .. ,1 A lliimr, Y .M ,W Y , V, Y Y W .. ff? tf::EZf'147i?'Tf.f?3f ff-T f3ff5if- 1'-'XT' :'2fi--51555 YQ f A Page Tbiriy-seven
