Among the pears Patten and Bantam both did well generally, bu 

 Patton seems somewhat hardier than Bantam. 



At Pittsburg, the Superior plum was hardier than Pipestone. Under- 

 wood was satisfactory in Colebrook, but Kaga was subject to winter in- 

 jury. Mount Royal is less hardy and less vigorous than Pipestone. 



The Nanking cherry did poorly in all sections. 



Among the small fruits red raspberries did better generally than 

 strawberries. Little or no winter killing was evident with the red rasp- 

 berry. Latham and Indian Summer both do well although Latham was^ 

 more productive. Whereas, Fairfax developed runners more freely than 

 most of the other varieties, strawberries, in general, did not develop run- 

 ners readily. 



The Kendaia grape has proved a failure where not protected by 

 snow. Beta killed back slightly at Colebrook, but was much more satis- 

 factory than Kendaia.

Strawberry Improvement 



Crosses were made in the greenhouse between previous hybrids of 

 cultivated varieties selected for late maturity of fruit, vigor, freedom from 

 disease, and high yield and quality. Also, crosses were made between 

 these types and the best selection from hybrids of cultivated and native 

 wild types. During the summer, the latest maturing variety selected from 

 previous crosses was crossed with Borden, a late blossoming Canadian 

 variety. To date all the seedlings show great vigor and freedom from 

 disease.

The Use of Mailing and Other Apple Rootstocks 



Observations of the rootstock and body stock planting at Gilford this 

 season indicate that Red Spy makes a more vigorous growth on all body 

 stocks than does either Mcintosh or Cortland, and that Red Spy over- 

 grows the body stock of Virginia Crab. Red Spy trees, on Mailing No. 

 4 root compare quite favorably with standard trees of the same age, that 

 is, six years. The Cortland and Mcintosh on Mailing No. 4 grow some- 

 what slower and appear to be quite weak unless located on the better soils 

 in the orchard. On the best soils, trees of Cortland and Mcintosh make 

 very good trees. The Cortland variety looks well and makes a fine ap- 

 pearing tree on Virginia Crab and on Florence Crab body stocks. It is 

 quite evident that body working has delayed the development of the trees 

 as compared to those trees grown from a bud. 



A progress report on the interstock planting will appear in the next 

 issue of the A. S. H. S. Proceedings. 



Annual measurements were made of the several varieties on the dif- 

 ferent Mailing stocks. Northern Spy trees on Mailing No. 1 make a fast- 

 growing tree that has come into fruiting earlv.
