nailed; in this floor should be placed a wooden chimney, nine inches square, on the most convenient part of the inside next the wall, with a wooden register at a convenient distance: this chimney is intended to let off the great smoke that arises in the kiln at first lighting fire, particularly if the wood be moist or green. When this has gone off, and the fire burns clear, the register may be shut within a few inches, in order to keep up a small draft. It would have been proper to state that joists, intended to support the floor of this kiln, should be levelled off to one inch, top and bottom, so as give the fire a better chance to act upon the malt; these joists should be further paid as soon as, or before, laying down, with a strong solution of alum water; as also the bottom face of the boards laid on them, which should be first planed; the inside of the chimney and register should be also paid with the alum solution. On the top of the kiln should be placed a ventilator to draw off the steam of the malt, this may be done by means of a loover or cow; the latter turns with the wind, the former is stationary.

There should be skirting boards, nine inches deep, to lie close to the floor and walls of the kiln, plastered with hair mortar on the top. This construction of kiln has been introduced by the Dutch, and will be found the most economical of any, joined to the peculiar advantage of being capable of drying malt with any kind of fuel, without danger of communicating any sort of bad flavour to the grain, while the heat can be securely raised to 120 degrees without any danger of ignition or burning; a higher heat is not wanted to dry pale malt. Of this, however, I have some doubts, as wood is a non-conductor of heat, and possibly is not susceptible of transmitting such a heat to the malt without danger of ignition. I should think that thin metal plates, one foot square, cast so as to lap on each other, or tiles, of the same make or form, would be a better covering; they certainly would convey the heat more rapidly and securely to the malt or grain intended to be dried on it, never requiring less fuel than the wooden covering, and precluding all danger of fire.

Drawing of vats above ground


A new and economical construction of Vats for keeping Beer, which, in this way, may be rendered fire proof, whilst, at the same time, it secures a temperature for the liquor equal, it is expected to the best vaults: it further affords the convenience of having them above ground.

These vats may be constructed in different forms, either square, oval, or round; the latter I should prefer, as stronger, and less liable to leak. These circular vats, to save expense, may be bound with wood hoops instead of iron ones the splay to be given them as little as possible barely sufficient to have the hoops tight, and the vessel staunch. The bottoms of these vats should be elevated at least three and a half, or four feet from the ground, and solidly bedded in clay, earth, or sand; the clay, if convenient, to be preferred. As the earth rises, at every five or six inches, around these vats, it should be firmly pounded down and compressed, as in the case of tanners' vats; and this mode of surrounding the vats with dry earth well pounded and rammed is continued to the top; a stout, close, well-fitted cover of two inch plank is then placed on each vat, with a hole sixteen inches square, to let a man down occasionally; this hole should have a short trunk of an inch and a half plank firmly nailed to its sides, and about fourteen inches high; then a covering of earth, twelve inches deep, should be placed all over the tops of these vats, and this earth well rammed and compacted together; and when levelled off, covered with composition or a floor of tiles. Each of the trap doors should have a well-fitted, wooden cover on the top, with a ring of iron in the centre; this cover should be made fire proof on the outside. The brick wall in front of these vats need not, I apprehend, exceed fourteen inches thick, if of brick, just sufficient to resist the force of pressure from ramming the clay; vats thus placed, with their contents, may be considered fire proof, and possessing as cool a temperature as if placed fifteen feet under ground; joined to this, they will last six times as long as those in cellars or vaults, although bound in iron, at a considerable higher expense. Two ranges of these vats may be placed in one house, leaving a sufficient space for a passage in the centre, with a window at each end to light it. I have never before either heard or read of this construction; but I have little hesitation in saying it will in many cases be found preferable to the present mode of placing vats—it being more convenient, cleanly, economical, and secure, and, to all intents and purposes, as effectual in point of temperature as those expensively placed deep under ground. Under the inside of the head of these vats, and across the joints, should run a piece of scantling six inches wide, and four inches deep, with an upright of the same dimensions in the centre, in order to support the covering on the head, and to prevent sinking, or swagging, from the weight of the covering that will be necessarily placed over them, which will be from six to ten inches thick.


Grinding, how substituted for.

Malt, for brewing, may be prepared in three different ways, by grinding, bruising, or pounding; modern practice, however, almost universally gives the preference to bruising between metal rollers. This preference, where malt is of the very first quality, may be justified; but where it is of an inferior quality, which is but too generally the case, grinding with stones is preferable, as more capable of producing a fine grist, which, with indifferent malt, is important, as it will always produce a richer extract, by being finely, rather than coarsely ground; and it is more soluble in water of suitable temperature than that malt which is only bruised or cracked, and for this simple reason, that all imperfect-made malt has a great proportion of its bulk unmalted, and, of course, in a crude hard state, which will partially dissolve in water if ground fine, but will not dissolve at all if only cracked or bruised. A further object of the brewer's attention should be to prevent the dispersion, or waste, of the finer parts of the malt, so apt to fly off in the grinding, if not prevented by having the malt bin close covered, as well as the spout leading into it from the stones; trifling as this precaution may seem, it is well worth the brewer's attention. Here it may not be improper to observe, that in all cases of horse, or cattle mills, where the shaft of the main wheel is perpendicular, no better ingredient can be placed in the chamber of the lower box than quick silver, which is far superior to oil or grease, and will not require renewing for a long time. The brass of a mill, managed in this way, might be expected to last twenty years, and the movement smoother and easier. This economical substitute for oil and grease can, with equal advantage, be applied to water mills, whether their shafts be horizontal or perpendicular; in a word, to all kinds of machinery, where the preservation of the gudgeons and brasses are an object.


Malting.

The production of good malt is, without question, the key-stone of the arch of brewing; therefore the brewer's attention should be invariably directed to this point, as the most difficult and important part of his operations. The process of making malt is an artificial or forced vegetation, in which, the nearer we approach nature in her ordinary progress, the more certainly shall we arrive at the perfection of which the subject is capable. The farmer prefers a dry season to sow his small
