SECRETARY'S REPORT. 225 



fated. Mr. Lawes, than whom there is no better authority, has 

 recently published a table "showing the estimated value of the 

 manure obtained from the consumption of one ton of different arti- 

 cles of food; each supposed to be of good quality of its kind." 

 We have reduced the -gross ton to our common ton of 2000 lbs,, 

 and given the price in dollars and cents. The following is the table : 



Mr. Lawes has been engaged for many years in experiments on 

 this subject, and we have no doubt that the table correctly states 

 the relative value of the manures obtained from the different foods ; 

 that is to say, if the manure obtained from the consumption of a 

 ton of hay is worth $6.43, that made from a ton of clover hay is 

 worth $9.64, or half as much again — and this is true everywhere. 

 The estimates are on the value of manure in England, and are 

 undoubtedly correct ; but of course the figures are only true rela- 

 tively where manures of all kinds are of less value, as is the case 

 in*the newer sections of this country. In the vicinity of this city, 

 manures are quite as high as in England, and here the estimates 

 may be adopted without any qualification ; and the same is true of 

 a great portion of New England, and nearly if not quite, through-
