tilizer treatments on suppressing Inrush once it had been checked by 

 cutting was studied. Fertilizing also increased the amount of graz- 

 ing on the plots and, consequently, the browsing on new brush shoots. 



There has been some greater response to lime on those plots where 

 the pH was below 5.00 but this has not been uniform. On the 12 

 farms with a pH on untreated soil of 5.06 the response has been 

 greater with more grass and clover coming in than on 5 farms with 

 a pH of 4.88. Lime and superphosphate have had a suppressing ef- 

 fect on ferns (P. aquilina, D. punctilobida, P. acrostichoides) and blu- 

 ets. Lime has also reduced the vigor of blueberries. 



With a low pH at the start. 4.79, and an increase to 5.18, on 8 plots 

 response in greater amounts of clover and g"ood grasses and less 

 Itrush regrowth was good only on 5 plots ; while with a relatively 

 h.igh pH at the start. 5.20, and an increase to 5.36 on 9 farms response 

 was poor on only 1 farm. It would ap])ear that in order to get 

 good response from superphosphate and complete fertilizers a pH of 

 5.0 or higher is desirable and then response is not only due to fer- 

 tilizers but to lime. The nitrate of soda plots showed a stimulating 

 effect on brush and ferns and poor grasses with no tendency to bring- 

 in clover. On one plot nitrate of soda did reduce the amount of moss. 

 The superphosphate and potash plots were generally poorer than the 

 lime and superphosphate or lime and complete fertilizer, and were 

 iisualh' as good as the comiilete fertilizer alnne. (Purnrll Fvnd)

The Marketing of Small Fruits 



Field work has been comi)leted and a publication will be issued 

 shortly. The objective of this study has been to bring together facts 

 concerning production, varieties, methods of sale, and prices obtain- 

 ed, in order to learn what opportunities exist in production and sale 

 of small fruits, how local markets may be more fully utilized, and 

 what may be done with surpluses should the}" arise. Blueberries are 

 the only small fruit produced in surplus quantities, and these are 

 \\\\(\ varieties. Other small fruits usually sell at premiums in local 

 markets, and at prices above those of most other states.

Economies in the Purchases Made by Farmers 



This study in economies in the purchases made by farmers, in 

 charge of L. A. Dougherty, has been undertaken in order to learn 

 more concerning: 



(a) Practices used by farmers in making purchases of production 

 and some types of consumer goods ; 



(b) What economies are available — and utilized — as may be in- 

 volved in :
