gallons of beer. tGood porter requires from 16 to 18 quarters for that quantity. Bee sar ® sometimes made with the addition of other farinaceous matter to the malt; hutj^hen the latter constitutes the main portion of the grain, the malting of the otherhinds of corn becomes unnecessary, for the diastase of the barley-malt changes thestarch into sugar during the mashing operation. Even with entirely raw grain, beeris made in some parts of the Continent , the brewers trusting the conversion of the?l arcb .* nto sugar to the action of the gluten alone, at a low mashing temperature, on^^Priftciple of Saussure’s and KirchofPs researches.

c °lor of the beer depends upon the color of the malt, and the duration of the0l j m the copper. The pale ale is made, as we have stated, from steam or sun-driedand the young shoots of the hop; the deep yellow ale from a mixture of paleyellow and brown malt; and the dark brown beer from well-kilned and partly car-onized malt, mixed with a good deal of the pale, to give body. The longer and mores rt >ngly heated the malt has been in the kiln, the less weight of extract, aetcris paribus,°es il afford. In making the fine nild ales, high temperatures ought to be avoided,na the veast ought to be skimmed oT, or allowed to flow very readily from its top, by?? eans °f the cleansing butt system, so that little ferment being left in it to decomposee re st of- the sugar, the sweetness may remain unimpaired. With regard to porter,a certain breweries, each of the three kinds of malt employed for it is separatelyashed, after which the first and the half of the second wort is boiled along with the°le of the hops, and thence cooled and set to ferment in the gyle-tun. The thirdfawn wort, with the remaining half of the second, is then boiled with the same hops,javed by the drainer, and, after cooling, added to the former in the gyle-tun, when theo mast he well roused together.
