THE TESTING OF HUMOGEN 145 



were rather smaller, showed the peculiar rich bluish- 

 green tint that is associated with vigorous growth, 

 and in the case of the humogen-treated plants there 

 were clusters of red fruits, while on the others the 

 fruits were only beginning to change from green to 

 red. The tomatoes on the humogen-treated plants 

 were indeed over-ripe, as they had been left on the 

 plants so that full opportunity might be given for a 

 comparison between the humogen-treated plants and 

 the others. Also, as the accompanying illustration 

 demonstrates, the humogen-treated plants showed a 

 greater quantity of fruit than the plants not treated. 

 In one of the houses near to the tomato houses a 

 somewhat similar experiment had been conducted 

 with the Guernsey Runner Bean. In this case 

 humogen-treated beans have made striking progress 

 both in growth and in quantity of fruit. They 

 stood several inches higher, and had large, well- 

 formed leaves, showing a deeper green than that on 

 the plants near by. From both groups of plants pods 

 had been pulled, and neither group had as yet 

 finished fruiting.* Already there had been a marked 

 increase in yield ; the humogen-treated plants showed

 received from Mr. Holmes giving the weights of beans pulled 

 from two typical plants. They are
