A. It prevents the atmosphere from penetrating 

 it, for the less the dung is penetrated by the air the 

 less it ferments. 



Q. What principal defects are noticeable in this 

 country with regard to the treatement of dungs ? 



A. The principal defects in the treatement of dungs 

 are the following: !» few or no litters are used ; the 

 employment of tree leaves, weeds, grass from weed- 

 ing, ferns, swampy or ordinary earth is neglected, 

 which would have the effect of holding the urines 

 and liquid parts of the dung and would double its 

 quantity ; 2° the dung is thrown carelessly in front 

 of the stable and no pains are taken to prepare be- 

 fore hand earth platforms to receive it ; 3® the 

 spot where the dung is thrown is often hollow, 

 or is composed of light and sandy soil, so that the 

 rain water in washing the dung carries away the 

 liquid manure that is to say the liquid part of the 

 dung, several feet under the ground ; 4° farmers often 

 lay their duiig in small heaps on the snow, or on 

 their pastures during the hot days of June and July, 

 so that when the time of burying it has come, it has 

 been all washed, has become spongy and is hardly 

 worth more than straw ; 5*^ farmers are often seen plac- 

 ing large dung heaps in the neighbourhood of ditches 

 or streams, into which all the liquid manure runs.
