APPLE EXPERIMENTATION AT MINN. UNIVEESITY FARM.

blighted, a few have died from other causes, but the orchard as a 

 whole is in excellent condition and of great possible value.

Orchard "E" was planted in 1900 on the open prairie and was 

 intended as a model orchard. It contains 488 trees, including sixty- 

 five kinds. This, too, is in excellent condition and promises to be 

 of much interest. It has borne but little fruit. 



Cultivation. All the orchards at University Farm are kept cul- 

 tivated throughout the growing season, and on the approach of 

 winter are plowed. The purpose of this plowing is to leave the soil 

 loose in winter to serve the same purpose as the dust mulch in 

 summer.

In addition to the apples which are growing in the orchards we 

 made a collection in 1890 of twenty varieties and species of wild ap- 

 ples from the Arnold Arboretum. Some of these have proven 

 especially hardy and desirable in every way, and we are trying to 

 determine their value as hardy stocks for the prevention of root- 

 killing in our orchards. We have paid special attention to raising 

 seedlings of the wild crab apple (Pyrus baccata) and have raised 

 something over 40,000 in the last two years.
