No. 1 cost in December, 1884, 8Z. 5s. per ton on rail, which was 
about the average price of the cakes given in the former Table 
of richer cakes. The great difference between these two sets of 
analyses of American cakes leads me to remark upon the 
impossibility of judging with any certainty whatever of the 
relative qualities of cakes when only a superficial examination 
of them is relied upon. 
Of materials used to adulterate linseed-cake, or not properly 
removed by screening, the principal ones detected have been 
locust-bean, niger-seed, cotton-seed husk, rape, polygonum, rice 
and other starchy bodies, and fine dust or sand. In two cases 
castor-oil bean has been detected, in each instance the cake con- 
taining it having proved fatal to stock feeding on it. The 
percentage of sand or dirt has in several cases been very con- 
siderable, and is then, I consider, apart from the question of 
deterioration in the actual value of the cake, highly objection-
