"Throwing out of the account the Yl pounds of carbonic acid, we have 213 pounds of earthy 

 matter. An acre of wheat needs, to feed both seed and straw, 17 pounds of phosphoric acid. An 

 acre of good clover will furnish 18 pounds. That quantity of wheat needs 2 pounds of sulphuric 

 acid. An acre of clover will supply 7 pounds. The former needs 1 pound of chlorine — a substance 

 that forms 60 per cent, in common salt — clover will furnish 7 pounds. Wheat (an acre) needs 16 

 pounds of lime. Clover will supply 70 pounds. Wheat needs 13 pounds of magnesia. Clover will 

 supply 18 pounds. Wheat needs 24 pounds of potash and soda (with an excess). Clover will furnish 

 77 pounds. Wheat needs 121 pounds of silica, of which clover can only furnish 16 pounds. Except 

 silica, or sand, it will be seen that an acre of good clover yields all the several minerals needed by 

 a crop of wheat; and some of the more valuable ones, in large excess. In its organic elements it 19 

 not less abundant.

" It is particularly worthy of note, that clover yields more than twice as much nitrogen as both 

 the wheat and straw require. It is proper to state, that to make 3,693 pounds of perfectly dry clo- 

 ver, one must have 4,675 pounds of clover hay. But in plowing in clover for wheat, we gaia all 

 the stubble and roots, in addition to what the scythe clips in mowing." 



The practical experience of wheat growers justify the opinion, that, as a preparation for a wheat 

 crop, there is nothing superior to the turning in of a crop of clover. Why such is the fact, we shall 

 now proceed to show, by constructing a comparative table, showing the constitution of clover and 

 wheat, and as illustrated by the preceding extracts from Dr. Lee's admirable paper. The quantities 

 of each is the product of an acre, good crops being presumed to have been grown in each instance. 



After studying the soils and crops of otlier sections six years, we are about to resume 

 our researches in Western New York, with increased confidence in its incomparable 

 agricultural resources. Talking, and writing, signify but little ; and we beg the co-ope- 

 ration of every friend of the forming interest that results in practice^ to be seen by all 

 men, may confirm the propriety of investigating the laws of nature that govern the 

 growth of all agricultural plants, and the wisdom of being able to understand and obey 

 these laws, which are the enactments of the Creator. •» 



In the young men of Western New York, we recognise the best material in the world 

 for the formation of a society to promote agricultural sciences. If these gentlemen are 

 unwilling to identify themselves with a movement of this kind, we shall regard it as 

 hopeless to attempt any thing elsewhere of an intellectual character, for the elevation of 

 the agricultural profession. No young man can ever regret that he has studied and 

 mastered the sciences of tillage and husbandry. No matter what position in life he may 

 attain to in the brilliant future of this Republic, his profound knowledge of the 

 laws of agriculture and horticulture will secure to him the respect of all whose good 

 opinion is worth having. To a youth of honorable ambition, what is a dollar a year ? 

 After the society is organized, it will determine the investigations to be undertaken, the 

 length of time they are to be prosecuted, and the reports to be made for the instruction 

 of each member whose name will stand recorded as one of the first patrons of agricul- 

 tural science in the United States. No money is to be paid until one thousand names 

 are obtained, and a treasurer duly appointed to receive the funds of the association. If 

 it is not possible to raise a thousand dollars a year to promote agi-icultural science in the 

 United States, the historical fact shall be recorded to the enduring disgrace of the age 

 . in which we live. There is scarcely a county in the Union that does not cheerfully sup-
