GENERAL RESULTS 191 



and flower, and perfectly balanced growth, with 

 increase in size, were well marked in the treated 

 plants. 



LETTUCES. A series of experiments carried out 

 in a dry spring showed a superiority of the peat over 

 dung of 123 per cent., and of the peat over artificial 

 manure of 176 per cent. The plants were markedly 

 good-looking, and hearted well. 



LILIUM HARRISII. In addition to showing the 

 characteristics usually following the use of peat with 

 pot plants there was an average increase of 8 inches 

 in height, though the pots were smaller than those 

 ordinarily used. The number of blooms per plant 

 was usually six or seven. 



MAIZE. Remarkable results were obtained with 

 experiments conducted in sand culture with maize to 

 testthe effect of auximones. The weights of the dried 

 plants under different treatment were as follows: 



Grammes. 



Sterilized sand and distilled water . . 66 



Sterilized sand and Detmer's solution . . 215 

 Sterilized sand, Detmer's solution, and 

 phosphotungstic fraction from humogen 

 (17 parts in 1,000,000) . . . . . . 255 



Sterilized sand, Detmer's solution, and 

 Silver nitrate fraction from bacterized 

 peat (0-35 part in 1,000,000) . . . . 325 



MARROWS (Bush). When marrows were treated 

 with artificial manures the average weight of the 

 fruits obtained per plant was 16 pounds 5 ounces. 

 When treated with peat the fruits weighed 37 pounds 

 ii ounces. The plants fruited a week earlier, and 

 continued bearing after the others. 



MUSTARD. Peat treatment gave an increased 

 yield of 174 per cent. The leaves were darker all
