The data are of some interest for New Hampshire conditions because they 

 demonstrate that only those varieties designated as early or second early are of 

 value to plant here.

The showing made by the dwarf varieties is particularly poor. Plants of the 

 dwarf varieties are attractive when offered for sale by grocery stores, because 

 they are upright and sturdy. For this reason they are purchased by many 

 people, but rarely if ever yield enough fruit to pay for the original cost of the 

 plant. 



Forest Plots. 



Two projects are being carried forward by K. W. Woodward (Forestry): 

 the growth of forest plantations, and the thinning of immature stands of white 

 pine. 



No new features have developed in the plantation work, but the thinnings 

 have now reached the stage where the good results are becoming more and more 

 evident. There is a striking difference between the thinned and unthinned 

 plots. 



The stakes around the active plots are- being renewed. 



Methylene Blue Tests. 



PubUcation on this project, which has been conducted by J. M. Fuller, 

 H. F. De Pew and B. E. Huggins of the Dairy Husbandry Department to 

 ascertain the desirabihty of the methylene blue reduction test as a simple and 

 inexpensive method of determining the keeping quaUty of milk, has been made 

 during the year. The data assembled showed that:
