A series of experiments with similar saline manures was also 

 made with Potatoes. Twelve squares were planted with Bread 

 fruit Potatoe on the 20th of March. The cuttings were as nearly as 

 possible of the same size, and came up tolerably regularly. On the 

 12th of May, when most of the young plants were from two to 

 four inches above ground, the manures were applied ; they were not 

 sown broadcast over the whole bed, but sprinkled as uniformly 

 as possible on each side of the row of young plants, to a distance of 

 about six inches. The salts used were the same as those applied 

 to the wheat, with the exception of the Silicate of Potash, namely, 

 the Phosphate, Muriate, and Sulphate of Ammonia, Sulphate, 

 Muriate, and Nitrate of Soda, Sulphate and Muriate of Potash, 

 Sulphate and Phosphate of Lime, and Sulphate of Magnesia, 

 whilst the twelfth square was left without any manure as a standard 

 of comparison. In about three weeks after applying the manure, it 

 was evident that four of the squares, namely, those to which the 

 Salts of Ammonia and Nitrate of Soda, had been applied, were dis- 

 tinguished from the others by more vigorous growth, and rather
