Discussion. 

 Mr. C. Moore — In the process of drying is the charge subjected 



Dr. Thompson — It is subjected in that apparatus to a heat which 

 is known, namely— something more than 300 degrees Fahr. 



Mr. MooRE — Because there can be no question about that the 

 roasting process destroys the value of it as manure. The City 

 Council have adopted the plan of burning the refuse, and it leaves 

 little behind it except charcoal. I have tried it in many places 

 and find it to be of very little value ; but where the refuse is 

 allowed to accumulate and to decompose in bulk then it becomes 

 a most valuable manure, and when it is decomposed there is really 

 no smell from it. But the smell when it is removed is simply 

 abominable. I had a large quantity of the refuse carried to the 

 Centennial Park — I suppose something like 1000 tons of it — and 

 there was no complaint whatever until it was moved, but the 

 moment it was moved the smell was frightful, so much so, that 

 the residents in the district petitioned against using it, and I was 

 obliged to stop for the time being, and when the winter came I 

 used the remainder. It was perfectly astonishing the effect of 

 that material placed over the sand. Where I stopped the line of 

 demarcation was distinctly marked. Where I did not put that 

 stutt^ the grass was very thin, but where I put it there was a fine 

 layer of grass. With regard to Poudrette— I had some of this 

 Poudrette (I do not know whose it was) to try the experiment 

 with, and I set apart a small portion of ground and divided it 

 into two. One portion had no poudrette on it, and the other had 

 poudrette put on in some quantity, and I am sorry to say that 

 there was no advantage at all from the portion which had poudrette 

 put upon it. The experiment was simply unsuccessful. I have 

 not been asked to give a certificate, but if I should be asked I 

 shall have to say that it is of no use. I am satisfied that in the 

 ■drying process there is some principle by which the fertilising
