GENERAL RESULTS 195 



and soil is giving considerably better results than 

 his own soil mixture. 



SCHIZANTHUS. The plants proved finer and 

 heavier flowered, and the individual flowers were 

 larger than the controls. 



SCUTELLARIA CosxARiCANA. The plants were 

 grown with humogen and soil as against a complete 

 manure. There was differential improvement in the 

 case of the humogen-treated plants in root develop- 

 ment, nature of foliage, symmetry, and size. The 

 increased sturdiness of growth was notable, while 

 the flowers were distinctly heavier and earlier. 



STREPTOCARPUS. Excellent growth was made 

 with glossy foliage and abundance of flower. 



SWEET PEAS. The effect of humogen on sweet 

 peas is marked. There is increase in growth, height, 

 and length of flower-stems, and intensification in the 

 colour and veining of the bloom. The foliage is 

 healthier looking and deeper in tint. The Bide 

 Challenge Cup was won this year (1915) by an 

 amateur at the National Sweet Pea Society Show by 

 blooms from plants grown with the aid of humogen. 

 The second prize was also won by a grower who had 

 used humogen. The same grower (who got first 

 prize) has won at different shows this year five first 

 prizes and one second prize, in every case with 

 humogen-treated plants. In two gardens where 

 humogen was used streak was absent, though un- 

 treated plants collapsed from the disease. 



TOMATOES. Stimulation of growth is very marked 

 with tomatoes. Rapid growth takes place, but 

 plants remain short- jointed and small foliaged,
