RESULTS. 



*0=ordinary agar; W, whey agar; L, 4% lactose agar. 



COMPARISON OB' GROWTH OF DAIRY GERMS_, ETC. 



The lactic germs grow equally well on ordinary and on lactose agar 

 while the associative germs prefer the ordinary agar. However the re- 

 sults are not especially marked in either case. 



REPOKT OF THE HORTICULTURIST. 



To the Director: 



Sir : — I herewith submit the following report of my work as horti- 

 culturist for the past year. It may be summarized as follows: 



1. The South Haven Sub-station. 



2. Cooperative Experiments. 



3. Consultations upon Horticultural Matters, 



4. Correspondence. 



SOUTH HAVEN SUB-STATION. 



During the year the charge of the station has remained in the hands 

 of Frank A. Wilken and a general report of the work performed during 

 the growing season of 190T, was given in a bulletin submitted early 

 in the spring. 



For the most part, everything is in excellent condition although, as 

 stated last year, the freeze of October, 1906, killed back the most of 

 the grapes and bush fruits and destroyed the young peach trees and 

 some of the Japanese plums. However, the apples, plums, pears and 

 cherries escaped with little, if any, injury and are looking well. The 

 plantation was made largely with the idea of testing the value of the 

 different varieties and as only two trees of a kind were used, it has 

 not been possible to carry on any very definite experimental work along 

 other lines. Two years ago, however, jjlantings of apples, peaches and 

 European and Japanese plums were made for the purpose of testing 

 and comparing merits of tillage and mulching for these fruits, using 

 various modifications. All of the trees are making a good growth but 

 it is as yet too early to reach any definite conclusions. 



Spraying. In addition to the general spraying of the trees which is
