3. A small quantity of clear lime-water, say one quart to a hundred gallons of juice, should be added the moment it is expressed, unless the juice shows acidity with litmus paper; in that case, no lime should be used, but a solution of sal-soda or soda ash should be added, until it is precisely neutral. 4. When the juice is neutral, free from excess of acid or alkali, it should be evaporated in such an apparatus as would finish its charge in 30 minutes; if the boiling power is too small, good crystallization can not possibly be obtained. The whole time occupied, from the cutting of the cane to finishing its boiling, should not exceed one hour. 5. To know when the boiling is finished, place a thermometer in the kettle, and continue to evaporate until it stands at 239 deg. Fahrenheit. If, when placed to run off after cooling, it should be found too freely boiled, the next time boil to 240 deg., or, if too light to run off, to 238 deg., and so on. 6. The kettle or boiler should be so arranged, that the moment it is done its charge should be thrown into a cooler, capable of holding a number of charges. The first charge should be left in the cooler with stirring, until the second charge is thrown in; then with an oar scrape the crystals found on the side and bottom of the cooler loose, and gently stir the whole mass together: the less stirred the better; so continue at the letting in of each charge, to stir gently; and when all is in the cooler, let the whole stand until it cools down to 175 deg.; then fill out into sugar-moulds of a capacity not less than 14 gallons. When cooled in the mould sufficiently, say fourteen hours, pull the plug out of the bottom of the mould, and insert a sharp point, nearly as large as the hole, some six inches; withdraw the point, and stand the mould on a pot to drip. 7. If the sugar is intended to be brown, leaving it standing on the pot for a sufficient length of time, in a temperature of 80 deg., will run off its molasses, and leave it in a merchantable shape; it will probably require twenty days. It can then be thrown out of the moulds, and will be fit for use. When moulds can not be obtained, conical vessels of wood or metal, with a hole at the apex, will answer equally well.
