240. The value of Barley depends much on the relative 

 hardness of its husk, and this appears to be influenced by soil 

 and manure in its culture. A soft thin skin adapts it better for 

 malting, and a light chalk soil is best suited to produce it of 

 this character. Fromberg has ascertained that the Kard Barley 

 contains less gluten and albumen than the softer kinds : thus

The effect of soil upon the Barley crop is known to all practical farm- 

 ergso that, in Great Britain, the terms barley-land and wheat-land are 

 the usual designations for light and heavy soils. On clay lands the pro 

 duce of barley is greater, but it is of a coarser quality and does not malt 

 so well, on loams it is plump and full of meal, and on light chalk soils 

 the crop is light, but the grain is thin in the skin and of a rich color, 

 and well adapted for malting. (Johnston.) 



241. Malt is Barley which has been made to germinate by 

 moisture and warmth, and afterwards dried, by which the vital 

 ity of the seed is destroyed. By this process, a peculiar nitro 

 genous principle, called diastase, is produced. This, though it 

 does not constitute more than l-500th part of the malt, serves
