278 Annual Report of the Consulting Chemist. 



coloured, first-class decorticated cotton-cake. This kind of cake 

 has lately risen in price ; but, considering- its high manurial value, 

 which may be assumed to be worth fully 5/. 10^. on an average, 

 and the good use to which it may be turned when it is given to 

 stock in conjunction with Indian-corn, locust-meal, and feeding- 

 meals abounding in starch and other non-nitrogenous constituents, 

 to supplement the nitrogenous materials in which decorticated cot- 

 ton-cake abounds, it is still one of the most useful and economical, 

 articles of purchased food, of which the farmer can avail himself. 



Green German rape-cake of good quality has become scarce in 

 England. Only a few samples of really good feeding rape-cake 

 were received for analysis last year. These were made from green 

 German rape or Riibsen seed, whilst the cakes which were made 

 from East Indian rape-seed were found, as in former years, too 

 much contaminated with wild mustard, and, in consequence, too 

 pungent to be a safe food for stock. 



A new feeding- cake, comparatively speaking, is cocoa-nut cake, 

 of which several samples were sent for examination. 



The following analysis shows the composition of a good 

 specimen of cocoa-nut cake : — 



Moisture 7*50 



Oil 10-56 



*Albuminous compounds (flesh-forming matters) .. 18*94 



Mucilage, sugar, ;md digestible fibre 43 '17 



Woody fibre (cellulose) 13 '17 



Mineral matter (ash) 6*66 



100-00 

 * Containing nitrogen 3-03 



Cocoa-nut cake resembles palm-nut kernel-cake in its general 

 character, and no doubt is a useful auxiliary food, but being 

 much poorer in oil than best English palm-nut meal, it is less 

 valuable than the latter for feeding purposes. The supply of 

 best palm-nut cake has not been equal to the demand, and, in 

 consequence, inferior samples of foreign palm-nut cake, poor in 

 oil, have found their way into England. 



Another press-cake, useful for feeding purposes, is olive-cake, 

 a sample of which on analysis yielded the following results : — 



Moisture 6*80 



Oil 20-33 



*Albuminous compounds (flesh-forming matters) .. 7*75 



Mucilage and digestible fibre 27-01 



Woody fibre (cellulose) 34-65 



Mineral matter (ash) 3-46 



100-00 

 * ContaiHing nitrogen 1-24
