6 COMMISSION OF CONSERVATION 



estimated, there is probably 8,000 to 10,000 tons of waste, an amount 

 of material now being buried annually, or otherwise destroyed. With 

 this in view, I got into communication with the Deputy Minister of 

 Game and Fisheries for Ontario, who kindly offered me every facility. 



Before commencing my work, I had to ascertain whether the facilities 

 on Georgian bay or lake Erie would best be suited to my work. It 

 was decided to open a small research station at Port Dover on lake 

 Erie, in view of the fact that I had not only natural gas at my disposal, 

 but also the all important factor a certainty of supply of such raw 

 material as I required. 



After selecting a site, I proceeded to ascertain what apparatus was 

 available. In this I found great difficulty, for, on all sides, I was told 

 nothing could be made or even adapted to my purpose for several weeks, 

 and possibly months. I had, therefore, to content myself with four 

 ordinary feed cookers which, of course, could only be operated at a 

 maximum temperature of 212 F., so far as digesting was concerned. 



For drying purposes I had to content myself with direct gas-fire heat 

 without circulation, and for moulding, I had to use an Enterprise chopper. 

 All other apparatus was on similar makeshift lines. 



However, I had to make the best of the apparatus available and I 

 am glad to say that I found it fairly capable of showing me approximately 

 what was obtainable from the waste in a qualitative way. 



On arrival at Port Dover, I had some difficulty in leasing suitable 

 premises, but eventually secured part of an old tannery very much out 

 of repair. In this, I erected what plant and machinery I could collect 

 in the time and I subsequently engaged a man and boy to assist me in 

 the work. 



I then entered into an arrangement with the fishermen to supply me 

 free of cost with such waste as I required, and, as a result, I took in for 

 treatment and research about half a ton of raw material every other day. 



CHARACTER OF FEEDS MANUFACTURED 



The waste I found very different from the material which I had had 

 previous experience with in other countries, particularly on the North 

 sea, and necessitated much more careful treatment than my make-shift 

 apparatus permitted. However, with certain data ki my posses- 

 sion, I proceeded to compound various live-stock feeds along the lines 

 I had previously operated, some eighteen years ago, in Germany. These 

 feeds were used experimentally at the Central Experimental Farm at 

 Ottawa.* I fear I was unable, with the plant at my disposal, to extract
