is much better to commence at a much later period of the day; by so doing they will have the advantage of night for cooling their worts, and with the assistance of fans or blowers, they can at all events, with few exceptions, get their worts to a temperature of 60° before letting them run into the gyle-tun. This temperature, in hot weather, is as low as it would be desirable to go, unless the tun rooms can at all times be kept considerably under the temperature of the atmosphere.
Fans or blowers, therefore, may be considered, for the reasons above stated, preferable to the best refrigerators.
REGULATORS FOR THE TUNS.
It is, no doubt, a very desirable object to have the means of regulating and keeping in check the temperatures of the worts during fermentation; but if for that purpose we employ chains of pipes fixed in the gyle-tuns, consisting of different metals joined with each other, it is liable to the same objections with regard to galvanic action as when such pipes are otherwise connected with the tuns, and will generally be found to be attended with effects nearly as injurious.
Moveable regulators are the best; they can be applied or removed at pleasure. In winter or cold
