 Lime Requirements of New Hampshire Soils. 



The importance of lime in the development of the extension project for 

 more legumes in the state has been emphasized more and more during the 

 past few years; anil again during the past year a general series of soil tests

 so that they are immediately available for the farmer. These samples of 

 soils are carefully preserved and kept for future studies. 



The following table shows the summary of the results of the past two

The Methylene Blue Method ok Estimating the Keeping Quality 



OP Milk. 



The plate method of estimating bacteria in milk is generally used in the 

 behef that it gives the most satisfactory index (1), of the keeping quality 

 of milk and (2), of the conditions under which it has been produced and 

 handled. However, many of the smaller cities and city milk plants of the state 

 lack the necessary laboratory faciUties for running the plate method. With 

 a view, therefore, of determining a whether satisfactory index may be ob-
