EXPERIMENT STATION REPORTS 97 



upon soils rich in organic matter; and thus- the use of stable manure 

 in large quantities upon land to be used either for a nursery or an 

 orchard, should be avoided, particularly if the soil is inclined to be 

 moist, is it provides the conditions that seem to be favorable to the 

 development of the disease. When the trees have galls upon the collar, 

 or upon the larger roots they should not be planted as they will never 

 make a desirable growth. 



The wooly aphis is also reported in many young orchards and in 



some nurseries. This is troublesome further south where it does con- 



/siderable injury to the trees and infested nursery stock should be very 



rigidly and effectively treated; the same remedies may be used for 



these as for the black peach aphis. 



EXPERIMENTS IN IRRIGATION. 



During the past season the rainfall was ample for the growing of 

 all our crops, except for a short time during the early part of July and 

 during the fall and so we were not able to secure any definite results 

 from the experiments we had planned. A single irrigation of the straw- 

 berries resulted in a marked benefit, while the use of water upon the 

 late cabbage and cauliflower in September, helped us to secure a good 

 crop, while without the use of water it would have been an entire 

 failure. 



THE SOUTH HAVEN SUB-STATION. 



The charge of the work at the South Haven Sub-station has remained 

 in the hands of Mr. Lyon, whose report will soon be issued as Bulletin 

 152. 



With the exception of the peach crop, which was greatly reduced by 

 the loss of the fruit buds in the winter, the crops have been good. All 

 the older trees are in bearing and many of the young pears and apples, 

 planted since the establishment of the Station, bore a few fruits last 

 year. The land is now nearly all occupied with trees, with the exception 

 of a small area especially reserved for small fruits; this will make it im- 

 possible to extend the planting as we would like but by top-working 

 the trees that have been tested we can provide for the addition of 

 promising new varieties. 



As the strawberries can be tested quite thoroughly at the College, 

 and as the land that is now occupied by them will be required for other 

 «mall fruits, it is thought best to make no other plantings of strawberries 

 :at the Sub-station. 



During the year trellises have been provided for the grapes in the 

 southwest block and a number of rods of tile have been laid in the 

 northeast block, which completes the tiling of the Station tract. 



CO-OPERATIVE VARIETY TESTS. 



As has been explained in previous reports, it has been the policy of 

 the department to utilize any surplus trees or plants of new varieties 

 for distribution. This plan has been continued the past year and we 

 now have the co-operation of a large number of experimenters, in most 

 -of the counties of the State, in this work. While the results have not,
