748 ANNUAL REPORT OF NEW-YORK 



api^earance or effects. On making a complaint, I was reminded 

 by the manufacturer of his request that I would give him pre- 

 vious notice. He then explained that his object was to select 

 seed free from mustard or other impurity. Since then I have had 

 no occasion to find fault with the cake from this manufacturer. 

 A sample of this was found by Professor Way to contain, of 



Moisture, _ 8.49 



Woody fibre, . _ 8.61 



Starch, gum, sugar, &c., _ 37.93 



Albuminous matter 31.42 



Oil and fatty matter, 10.65 



Ash, _ 2.90

I have occasionally bought German or Danish rape-cake; it is 

 made up in thick square pieces of a rich green color, and not so 

 hard pressed. An analysis of this by Professor Way gave, of 

 albuminous matter 30 and of oil 13.16 per cent. Until this sea- 

 son I had no grounds to find fiiult with this foreign cake, but was 

 satisfied to pay for it a higher price, owing to its superior rich- 

 ness in oil. In this season's importation I was led to suspect 

 some admixture of mustard-seed. On macerating a sample in 

 tepid water, I perceived an admixture of yellow husks, and like- 

 wise the smell peculiar to mustard. More completely to satisfy 

 myself, I sent a sample to Professor Way, w^ho reported it to con- 

 tain mustard. 



As dealers now charge a higher price for this material, for 

 food, in comparison with what they charge for it as manure, they 

 are clearly responsible for its being of a quality suitable for food. 



To prevent the cake becoming mouldy, I cover it over with 

 shells of oats which have been kiln-dried; chopped straw, if dry, 

 would equally serve the purpose; by this means its flavor is also 

 preserved^ — indeed, by keeping for a time, I find it becomes milder 

 in taste, and more easy to masticate. 



Management of Grass-land. — In describing the crops or pro- 

 duce adapted for dairy purposes, I think it proper to notice my 

 treatment of permanent grass, meadow and pasture. I reside on 

 the borders of a district in Yorkshire, over which you may travel 

 60 or 60 miles without seeing, except here and there, an isolated
