 LORD KINNAIRD'S EXPERIMENTS. 1 



" Lord Kinnaird has given the particulars of a very care- 

 ful experiment. He tried to test the comparative value of 

 manure kept in an open court with that kept under cover. 

 He selected the same kind of cattle, gave them the same 

 kind and quantity of food, and bedded them with the same 

 kind of straw. A field of 20 acres of uniform land was 

 selected. This having been equally divided, 2 acres out of 

 each 10 gave the following results : 



Potatoes grown with Uncovered Manure. 



Tons. cwt. Ib. 



First measurement 1 acre produced .7 68 



Second do. do. do. 7 18 99 



Potatoes grown with Covered Manure. 



First measurement 1 acre produced . 11 17 56 



Second do. do. do. . 11 12 26 



This shows an increase of about 4 tons of potatoes per 

 acre with the covered manure. 



" The next year the weather was wet, grain soft and not 

 in very good order, but the following was the amount of 

 produce : 



Wheat grown with Uncovered Manure. 



Wheat grown with Covered Manure. 



First . 53 5 61 220 of 22 



Second 53 47 61 210 of 22"
