its action and less caustic to germinating seedlings or the 

 fresh delicate rootlets of tender plants ; it can in consequence 

 be used with more safety in the spring in potato drills or 

 immediately beneath the seeds of swedes and mangolds, parti- 

 cularly on a light soil.

Table IX shows a series of analyses made by Dr. B. Dyer 

 of stable manure from London, such as is used in very large 

 quantities by farmers and market gardeners, whose distance 

 from London does not render the freight too great. The most 

 noticeable thing in the five last analyses is the very low proportion 

 of nitrogen that remains soluble ; the frequency with which the 

 stables are cleaned out in London, the open nature of the heaps 

 and the many turnings to which the manure is subjected in 

 collection and transit, all result in extreme aeration and a
