PRUCKl^DINCS OF TDK 



of disinfected manure, 'i'hey vkere also potted with J an inth 

 of manure at the bottom of the pots, in all cases the growth was 

 in favour of those with the manure on the surface. The Peren- 

 nials, Verlx'ua sororia. \'erbena teucrioides, and Hybrid Petunia, 

 willj I an inch of disinfected manure at the top of the pot grew 

 rcinurkHbly well, w ithout any .symptoms of injury j with ^ 

 an inch of the manure at the bottom of the pot, they aL^o grew 

 very well, but it was evident that those top dressed were more 

 vigorous and robust than cither those with the manure at the 

 bottom, or those in the soil without anv disinfected manure. 

 The following were tried with the manure in a liquid state, 

 viz., Impatiens tricornis, glandulifcra and Candida, all very strong 

 gniwing plants, and well adapted for trying the strength of the 

 substance. \'arious other plants have ;dso been watered with the 

 liquid, and in all cases with much benefit, more particularly those 

 kinds which naturally grow with great vigour. After various 

 trials it was found that only 1 part in 60 or about one pint 

 of disinfect td manure to eight gallons of water, should be em- 

 ployed, and then the plants should only be watered with it once 

 a week, or, if very slow growing sorts, once in two weeks. 

 The manure is very powerful, and taking the small portion 

 required and the price (about Is. Sd. per bushel) into considera- 

 tion, it has merit and deserves trying in the open ground on 

 a mucli larger scale 'i he principal objection to its general 

 introduction is, that it may be used too strong and so destroy 

 vegetation for the first season, or make plants sickly. If used 

 in a dry state it seems in any quantity almost sudden death to 

 some plants, acting in the same way as dry salt j it therefore 

 should only be used in a liquid state. It may be mixed with the 

 water and used in ten minutes afterwards just as well as if it had 

 been mixed ten hours ; it then seems to lose the deleterious 

 effects £0 destructive to vegetation.
