an extensive equipment and generous resources. The resignations 

 (luring the year atiected the membership of the staff but little. J. T. 

 Bairett resigned as assistant in botany and C. E. Lee, assistant chief 

 in dairy manufactures in the station, accepted a position as assistant 

 in dairy husbandry in the University of Wisconsin. The following 

 ap})ointments of assistants were made: I). L. James and L. R. Lang, 

 dairy husbandry; C. E, Durst, olericulture; IL W. Stewart, soil sur- 

 vey; E. W. Bailey, plant breeding; A, H. Nehrling, floriculture; and 

 AV. A. Ruth, horticultural chemistry. The experimental greenhouse 

 of the department of floriculture was enlarged by an addititon, 28 

 feet by 222 feet, which exactly doubled its capacity. No increase in 

 appropriations was granted the station by the legislature except that 

 the soil funds were raised from $25,000 to $()0,00() a year. This 

 increase is to be devoted to an extension of the soil survey and the 

 publication of the results of investigation. 



Progress is reported in all of the Adams fund projects under way. 

 Studies of heredity by the statistical method are made from herd 

 books for animals and from data on corn and other plant breeding 

 at the station. Sufficient data, especially on correlation of characters 

 in corn, have accumulated to warrant their publication, and a l)ulletin 

 is under preparation. An extensive study of heredity in milk pro- 

 duction developed a good case of false correlation, which is al)out 

 to be presented by means of an article to ai)pear in an impor- 

 tant scientific journal. The investigation of the effects of inbreeding 

 has made headway, but the results are not ready for discussion at 

 present. 



Plant-breeding studies were conducted with apples, peaches, 

 strawberries, and sweet peas. The station has 700 trees from apple- 

 bud selections made in the spring of 1008 and 400 trees grown from 

 selections in 1909. Of apple pollinations, 12^ per cent, and of peach 

 pollinations, 22.3G per cent, nuiturcd fruit. The most significant 

 result in the work with the strawberry was vigor of growth and 

 remarkable juoductiveness in many of the seedlings as compared 

 with the parent plants. Of sweet-pea pollinations 18.7 per cent were 

 successful. The .seedlings of all these different plants are untler 

 observation for the purpose of determining their value. In connec- 

 tion with the project on the chemical and physiological changes re- 

 sulting from varying rations, 20 steers were fed for thirty-four 

 weeks, and the data secured are being prepared for ])ublication. A 

 bulletin of progress has been issued on the investigation of liordeanx 

 mixture in its relation to orchard trees and piincipally to the foli- 

 age. The use of impure oi' improper uuiterials, carelessness in mak- 

 ing the mixtures, and iniprojier or ineffective application were ob- 

 served as the principal sources of injury. It was further found that
