GENERAL RESULTS 193 



PEAS. In one of many experiments there was a 

 31 per cent, gain in weight of the pods pulled for 

 eating. The plants were taller, and the pods were 

 both larger and more numerous. In another experi- 

 ment on peas grown for seed three rows untreated 

 gave 18 pounds of dry seed, while three treated rows 

 gave 28 pounds of seed, an increase in weight of 

 55 per cent., representing to the grower a money 

 gain of i8s. 3d. 



POTATOES. Compared with no manure, artificial 

 manures and dung, peat has given an increase in 

 potatoes over no manure of 123 per cent., over arti- 

 ficial manures of 75 per cent., and over dung of 

 41 per cent. These results were obtained in a light 

 sandy loam in 1913, the land not having been 

 previously cultivated for nine years. In 1914 the 

 same ground treated with humogen gave an increase 

 of 59*5 per cent, over land not manured. A part of 

 each of the plots manured in 1913 was left un- 

 manured in 1914. The land which had received arti- 

 ficial manures showed an increase of 27 per cent, 

 over the unmanured land, the peat-treated land 

 showed an increase of 83*3 per cent., while the land 

 that had received dung showed an increase of 37*7 

 per cent. The treated peat appeared to leave the 

 land as fertile the second year as in the season of 

 application. 



PRIMULA (Malacoides, Kewensis, Obconica, etc.}. - 

 All varieties of primula tested responded equally 

 well, the plants in each case showing 100 per cent, 

 superiority. The flowers were more prolific, and 

 individually larger and better coloured.
