gathered, foliage stripped off, and after various hormone treatments 

 buried in a peat and sand mixture with bottom heat of about 30°C. These 

 remained alive for months but showed no rooting. Others were buried 

 in outdoor beds in October and November. Many remained alive until 

 spring, but no rooting or callusing developed. 



No positive results were obtained in treating cuttings with dilute 

 solutions of potassium permanganate. (C. L. Stevens and Stuart Dunn) 



Woodlots in Farm Organization in Coos County 



A cooperative project for the Bureau of Agricultural Economics 

 and the New Hampshire Experiment Station has been completed. It was 

 found that woodland resources are not well distributed among the farm- 

 ers of the Colebrook area. Farmers in the area have attempted to adjust 

 the size of their herds and the acreage of crops to fit into an economic 

 unit, but they have neglected to give proper consideration to the wood- 

 lands in their plans. The income of the whole area could be raised by 

 a greater utilization of the available man power in slack seasons. An 

 analysis by the budget method indicates that many farmers could increase 

 their net income bv adding additional woodland and including a definite 

 woodlot management program in their farm organization. (In coopera- 

 tion with Bureau of Agricultural Economics.) (John C. Chandler)

Effect of Fertilizing Elements on Apples 



Further tests were made in an attempt to discover whether "arrow- 

 head" leaf scorch is a soil-plant relationship. Some evidence that such 

 is the case, at least in part, was offered as a result of pot tests during the 

 summer and fall of 1941. Soil samples were obtained beneath the tree 

 most severely affected by this scorch at the Hewitt orchards in Walpole 

 and beneath a normal healthy tree. The soil from beneath each tree was 

 put into one-gallon lacquered tomato cans. Soil from beneath the se- 

 verely affected tree received the following amendments : molybdenum, 

 calcium, magnesium, potassium, and zinc, also combinations of calcium 

 and magnesium, calcium and potassium, and potassium and magnesium. 

 One control received only tap water, another distilled water. 



Seedlings of Wealthy apples were planted in the pots. Growth 

 was best wherever calcium was used, the best growth being obtained 

 where calcium and potassium were used in combination. Good growth 

 was also obtained with magnesium alone and with potassium alone, also 

 with zinc. No growth occurred where distilled water was used, and 

 the plants died before the test was concluded. Those watered with tap 

 water grew very slowly and were not much larger at the end than at the 

 beginning of the test. No better response was obtained with soil treated 

 with molybdenum. Plants in pots receiving a combination of potassium 

 and magnesium failed to make appreciable growth throughout the period. 

 Leaves were severely scorched on trees making poor growth, although 

 the type of scorch occurring on these leaves was different in character 

 from the scorch observed in the orchard. Trees making the best growth
