We must now, as before, calculate what number of barrels must be turned out of the copper, so as that 36 may go into the gyle-tun. We use 2 lbs. of hops per barrel, 94 lbs., which will increase the quantity in the copper to 48½ barrels, and these will retain one barrel and at-half, or rather more, and about eight barrels will be evaporated on the coolers.

We find, in the gyle-tun, thirty-six barrels one firkin, at 26 lbs. gravity, or nearly so, at least correct enough for practice.
