110 YALE AGRICULTURAL LECTURES. 



to distinguish between two grasses otherwise very similar in 

 appearance, but of widely different nutritive value. Speaking 

 of the area under the grasses in European countries, Mr. Gould 

 made a forcible illustration of his subject by comparing the ag 

 gregate products in forage and cereal crops in France and 

 England. France has fifty-three per cent, of her cultivated 

 area under cereals, while England has but twenty-five per cent. 

 But, on the other hand, England produces five and one-ninth 

 bushels of grain for every individual of her population annually, 

 while France produces only five and a half bushels. Thus, 

 with less than half of the proportionate area under cultivation, 

 England produces within seven-eighteenths of a bushel per head 

 of what France does. This she accomplishes solely by means 

 of the manure furnished by her grass lands. Every acre of 

 English grain-land receives the manure from three acres of 

 grass-land, while in France the manure for each acre of grass 

 land is spread over two and a half acres of grain-land ! This 

 tells the whole story ; shall we profit by the lesson ? 



Judge FRENCH, of New Hampshire, gave his last lecture on 

 drainage this afternoon, much to the regret of the audience, if 

 I may judge by the triple rounds of applause by which he was 

 honored on taking his leave of us with a kindly expression of 

 good-will. He commenced by reading an extract from a letter 

 of Governor Hammond, of South Carolina, to Levi Bartlett, 

 recently received. The testimony of the distinguished Senator 

 is so directly in support of thorough drainage that I must give 

 it to you. He says : 



" Of my agricultural affairs, I can only say a few words. 

 The last years have been, in my immediate neighborhood, 

 average crop years, the last more than average. Yet with me, 

 owing to my absence, as far as my corn was concerned they 

 were not near as productive as 1857. My corn is mainly grown 

 on the 1,500 acres of inland swamp I have reclaimed, which 

 averaged me, in 1857, about fifty bushels per acre, in 1858, 

 about thirty bushels, and in 1859 about twenty. This looked
