fair profit ; on a Timothy sod the results on different plots 

 vary widely, and the average is a small increase, produced 

 at a cost greater than its value. 



XIII. — To determine which is the better practice : to haul 

 manure and spread directly on the field during late autumn 

 or winter, or to haul at the same time to large piles in the 

 field, to be spread and immediately ploughed in in the spring. 

 The results indicate that on land sloping moderately the 

 spring application is to be preferred, as the crops are more 

 than sufficiently large to cover the extra cost of rehandling 

 the manure. 



XIV. — To determine the value of alfalfa as a forage crop 

 for this locality. The results of a number of years are 

 quite discouraging, as, with the most careful attention to 

 tillage, manuring and keeping free from weeds, the crops 

 are exceedingly small, — hardly one-half what might con- 

 fidently be expected from clover under similar conditions. 



XV. — To determine whether Mand's Wonder Forage 

 Crop and Brazilian millet are different from Pearl millet. 

 Results indicate that these three crops are identical in every 

 respect, and that it will not pay farmers to give the high 

 prices demanded for the old and long-known Pearl millet 

 under a new name. 



1. — The Relative Value of Manures furnishing Nitro- 

 gen. (Field A.) 



A detailed description of the plan of experiment followed 

 in this field will be found in the twelfth annual report. The 

 materials under comparison are barn} T ard manure, nitrate of 

 soda, sulfate of ammonia and dried blood. These wherever 

 used are applied in such quantities as to furnish equal 

 amounts of nitrogen. There are three plots in the field 'to 

 which no nitrogen in any form has been applied. All the 

 plots in the field receive the same amounts of phosphoric 

 acid and potash. This experiment was begun in 1890, and 

 the crops which have been grown previous to this year, in 

 the order of succession, are : oats, rye, soy beans, oats, soy 

 beans, oats, soy beans, oats, oats, clover and potatoes. As
