Farm Manure. 131 



this reason it is recommended that wherever possible, the manure 

 should be hauled directly to the field and spread. It is the most 

 economical of time and labor, as it involves handling but once. 

 While it is true that it will be leached by the rain, nevertheless, 

 the soluble portion will be carried into the soil, where it is desired 

 to have it. When spread in a thin layer, it will not heat, so 

 there will be no loss from "hot fermentation;" and where ma- 

 nure simply dries out when spread on the ground, there is no loss 

 of valuable constituents. 



Wherever possible, haul and spread the manure daily as produced. 



Storing manure. When it is impossible to remove the manure 

 directly to the field, due to weather conditions or lack of avail- 

 able fields, the problem of properly storing it will present itself. 

 From what has already been said, it is apparent that the two in- 

 jurious processes, namely leaching and hot fermentation, must 

 be prevented. The effect of leaching may be prevented in two 

 ways; either by providing water tight receptacles so that the 

 liquid cannot run away, or by keeping the manure under cover 

 so as to protect it from the rains. The first method is in general 

 use in Europe, where pits or cisterns of cement or other imper- 

 vious material are built and in which the manure is stored. Some- 

 times a pump is provided, whereby the liquid portion is again
