CHEMICAL AND OTHER MANURES. 365 



Wrong cast, because these make up 1,010 instead of 1,000 ; 

 but we suspect that the contents are right in all the essentials, 

 and that the error is in putting down the deficiency as water, 

 which is probably in the original not stated other than in 

 ^ords — "rest water." It is not, therefore, of any conse- 

 quence as regards the value as a fertilizing matter. 54 

 bushels of soot and 6 lbs. of salt produced larger crops of 

 both the Altringham and Belgian white carrots than 24 tons 

 of stable manure and 24 bushels of bones, though at half the 

 cost. We cannot help wishing that there were some uni- 

 formity in the mode of recording the contents of anything 

 analysed, that we might be better able by comparison to 

 judge the value, and have more confidence in the gentlemen 

 who undertake such tasks. It is greatly to be regretted that 

 persons affording information cannot understand why one 

 man should produce one set of combinations, and another 

 chemist bring out another, when the two articles are the 

 same ; but so it is, and we have seen nothing yet to reconcile 

 us to the discrepancies which we have shown in the various 

 analyses of guano and of cow manure. There is nothing like 

 uniformity of terms, nor anji^hing reconcileable to common 

 people, in the fact of one giving a greater number of parti- 

 culars thon another; and we take leave to remind these 

 gentlemen chemists that notliing tends to advance science so 

 much as uniformity among the teachers and professors, and 

 their published opinions. Different tenns may in some 

 ^instances mean the same thing, but analyses made and pub- 

 lished for general information ought to be all reported in the 

 same language and terms, and the particulars given under the 

 same heads. If professors would but remember that they are 

 writing for the public, and not exclusively for one another, it 

 would be useful to them, and lead them to be intelHgible in 

 their lessons, that the public might learn with facility, and 

 study with profit and advantage. 



CHEMICAL AND OTHER MANURES. 



There are so many ways of applying manure, that the 

 quantity to be given is very problematical. He who sows 

 the manure with the seeds does not use the quantity which 

 is necessary when the whole ground is to be fertilized. 

 Chemical manures, and those which are rapidly soluble, 

 should not be put in much below the surface, because the
