night, and decant the liquid in the morning. Water 

 the moss once a week with humogen extract, and 

 in between times with ordinary tap-water. 



NOTE. (i) The weight of the bulb when planted 

 and its weight at the end of the season. 



(2) The same points as in the primula and radish 

 experiments. 



(3) The weight of the crop when tubers are grown. 



MODEL EXPERIMENT IV. 

 " Top-Dressing." 



The effect of humogen may be tried on any plants 

 or grass growing in the garden at any time from 

 March to September. Use 4 to 6 ounces to the 

 square yard, and work well into the soil. On grass 

 spread the humogen over the surface. For this 

 experiment humogen should be applied only in 

 plots. Thus, half a bed should be treated and the 

 other half not treated, so that improvements result- 

 ing may be noted. Apparently inconsistent results 

 must be expected in this experiment, as humogen 

 will not usually force a plant into fresh growth if the 

 normal resting stage has been reached for the season. 



NOTE all such points as described in the primula 

 and radish experiments, and especially compare 

 the condition of the treated and the untreated plants. 



NOTE TO FARMERS AND GARDENERS. 



As a measure of prudence it would be wise for 

 farmers and gardeners wishing to experiment with 

 humogen on a large scale to write direct to Mr. Alfred
