194 THE SPIRIT OF THE SOIL 



PYRETHRUM. Cutting was ten days earlier. Stems 

 were markedly longer, and the characteristic feathery 

 foliage better developed. 



RADISHES. A striking result has been obtained 

 with radishes grown in soil as against the same soil 

 and humogen. Two rows were grown against each 

 other. The weight of the best twelve plants in the 

 humogen row was 6| ounces ; of the second best dozen 

 5^ ounces. Only a dozen weighable radishes were 

 obtained from the untreated row, and they weighed 

 only 3f ounces. (Photo, p. 194.) 



RHUBARB. Early this year (1915) a very small 

 dressing of peat was given to a portion of a plot of 

 growing rhubarb. By June 5 the treated portion 

 was very much better than the untreated. It was 

 ready for pulling earlier, and growth continued 

 longer, stalks being pulled from it after growth had 

 ceased in the other part of the plot. 



ROSES. Excellent results have been obtained 

 with roses. The plants increased in vigour, and the 

 healthiness of the foliage and the colour of the 

 blooms were intensified. So well marked is the latter 

 quality that two beds of Dean Hole, one of which 

 was treated and the other untreated with the 

 peat, appeared as if stocked with two distinct 

 varieties of roses. The grower has secured five first 

 prizes in open competition this year. In one case 

 the better colour was the deciding factor between 

 first and second prizes. 



The intensification of the colour is especially 

 marked in the case of Marechal Niel. In the hands 

 of at least one well-known market grower humogen
