from the disease, and though small, were of good quality. The 

 Warren lot was planted to " peach blows," and yielded 156 bushels of 

 inferior and diseased potatoes, less than one-half of them being suit- 

 able for table use. This lot was fertilized with guano, phosphates 

 and manure from the reservoir. On the plain, around the corn field, 

 150 bushels of good potatoes, of different varieties, were produced. 

 On three acres of new land, rented of Mr. Brigham, never ploughed 

 before, were planted the Jenny Lind, Riley, Long Red and Worces- 

 ter seedling, fertilized with 300 pounds of plaster per acre, and a crop 

 of 301 bushels of fine potatoes harvested. One-half acre of Chenan- 

 goes was planted, but so injured by the rot that no further statement 

 is made. 



An acre and a quarter below the farm house has been planted to 

 the same variety three years in succession, as an, experiment, with an 

 annual application of 300 pounds of guano per acre — in 1854-5 in the 

 hill, and in 1856 spread on. The produce this year, 74^ bushels of in- 

 ferior potatoes ; in 1855, 119 bushels ; and in 1854, 189^ bushels. 



The season has been a bad one for potatoes, and in some instances 

 they have done quite as well without manure as with it. The above 

 experiments are therefore not so reliable as they would have been 

 under more favorable circumstances. In relation to guano on the 

 same land for a series of years, it will be seen that the trial on the 

 lot below the farm house, has resulted in a failure, and leads to the 

 belief that this fertilizer cannot be depended on for a caurso of years 

 for the potato, without some other adjunct as a manure. 



Cakeots. — Five acres were sown to the white and orange varietie3 

 and produced 47 tons and 1,700 pounds, equal to 1,914 bushels, of 

 50 pounds per bushel.
