When wheat arrives at a mill to be ground the sacks are received in the lower part of the mill, and hoisted by means of the sack tackle to the upper storeys, generally the uppermost. The mode of this operation is as follows, and it is performed with little bodily labour. The rope or chain of the sack tackle is firmly fastened round the mouth of the sack by the man below, who by means of a rope attached to a lever throws the tackle into gear. The sack then immediately ascends, without any further aid from the man, through the different trap doors, till it has arrived at the place of its destination. There another man is ready to receive it, who, as soon as he has landed it by pulling it on one side, throws the tackle out of gear, and returns the rope or chain to the man below. The wheat is then shot into a garner or bin, and thus the same process goes on till the whole load or cargo is safely deposited in the bin or garner. The wheat remains there till it is wanted to be ground, when, by means of a spout, it is conveyed to the hoppers below, and from thence runs in between the stones. In its progress to the stones, it may, or may not, be subjected to a cleansing process. The wheat being reduced to a flour, escapes through an aperture of the floor into a spout, by which it is conveyed to the trough. It is then either put into sacks, and drawn up again into one of the higher storeys, and deposited in bins over the dressing machines, or this is effected by a machine called an _elevator_, which performs the operation without the assistance of manual labour. In this bin the flour should be left till, at any rate, it is perfectly cold, but is will be all the better if it remain for three or four weeks, provided it be occasionally turned. From this bin it is passed, by means of a spout, to the hopper of the bolting mill or dressing machine, by which it is separated from the bran or pollard, and is then fit for use.
