i84 THE SPIRIT OF THE SOIL 



plant into active growth without producing a soft, 

 sappy plant that would succumb to frost. The 

 effect was to make the plants resistant, sturdy, and 

 vigorous. 



BRUSSEL SPROUTS. In this instance the effect of 

 testing peat against both artificial manures and dung 

 was to give an increased yield of better quality. 

 The buttons were hard, firm, and closely set, giving 

 a much greater average yield per plant. The plants 

 themselves grew taller, and the flavour was dis- 

 tinctly improved. 



CABBAGES. Growth was earlier and sturdier. 

 The plants showed a rich bluey green, denoting 

 perfect health. The hearts were larger, harder, and 

 crisper than in untreated plants. They were ready 

 for market earlier. 



CALLA. In calla the effect was very noticeable. 

 There was great profusion of bloom, and the root 

 action was excellent. The foliage was a rich deep 

 green, and the blooms were splendid. A top-dressing 

 of i ounce of humogen on a 10-inch pot full of food 

 more than doubled the growth in a month. 



CARNATIONS. One carnation specialist has had 

 plants 13! inches high in thumbs. They were then 

 still growing, and were the equal of plants which had 

 been grown in 3-inch pots, but without the peat. 

 Tested against various carnation specialities, the 

 peat-treated plants gave much more satisfactory 

 growth. They broke freely and flowered abun- 

 dantly. The plants grown in the humogen resisted 

 eel-worm, while those without it succumbed. One
