508 [Senate 



For 100 carmen's loads. You must bear in mind that a carman's 

 load is little more than half one of our farm loads, consequently my 

 manure would appear to cost 25 cents per cart load less than one-half 

 the price of that manure. 



I do not hesitate in saying that my soil has experienced greater ben- 

 efit from this manure than from any other I have ever used, that is in 

 reference to the condition of the soil after cropping. As an objection 

 to the use of this manure, it is said that the product of marshes and 

 swamps abound in the larvae of insects. By adding a due proportion 

 of lime, the larvse will not only be destroyed but also the grubs that 

 are already in the ground. 



AN ANALYSIS. 

 Of barren and improved Soils and the Muck used, by Dr. Field. 



We are indebted to Mr. Thomas Kerr for the following analysis of 

 soils. He observes there is no room for dispute as to the necessity of 

 exact knowledge of the laws of nature, if we would have truly successful 

 agriculture, I find Dr. Field's muck to be very nearly pure clay with 

 2h per cent of vegetable matter. 



The marl in composition consists of clay, 64 per cent ; of lime, (43 

 • — 71 to 100) — ^28 of lime. Vegetable matter in the proportion of 38. 



Carbonate of lime, 64 per cent. 



Vegetable matter, 4 do 



Clay, pure, nearly, 13| do 



100 parts. 



Barren Soil. 



Sand 74 per cent. Sandy loam consists of — 



Water, 3 per cent. 



Organic matter, 3 i do. 



Mineral matter, 93^ do. 



100 parts. 



Its organic matter — 



Soluble manures, 2 per cent. 



Insoluble do 1 i do. 



3i as above 



Its saline matter — 



Soluble saline matter, 2^ per cent.
