is our authority that among the ancients everything
<
lb
/>
which was mined was carried out on men's shoulders, but in truth this
<
lb
/>
method of carrying forth burdens is onerous, since it causes great fatigue
<
lb
/>
to a great number of men, and involves a large expenditure for labour; for
<
lb
/>
this reason it has been rejected and abandoned in our day. </

>Water-vessels differ both in the use to which they are put and in the
<

material of which they are made; some draw the water from the shafts and
<

pour it into other things, as dippers; while some of the vessels filled with
<
lb

water are drawn out by machines, as buckets and bags; some are made of

wood, as the dippers and buckets, and others of hides, as the bags. </

water-buckets, just like the buckets which are filled with dry material, are of
<
lb

two kinds, the smaller and the larger, but these are unlike the other buckets at
<
lb
/>
the top, as in this case they are narrower, in order that the water may not be
<
lb

spilled by being bumped against the timbers when they are being drawn out
<
lb

of the shafts, especially those considerably inclined. </

<
s
>The water is poured
<
lb

into these buckets by dippers, which are small wooden buckets, but unlike the
<
lb
/>
water-buckets, they are neither narrow at the top nor bound with iron hoops,
<
lb
/>
but with hazel,—because there is no necessity for either. </
s

<
s
>The smaller buckets
<
lb

are drawn up by machines turned by men, the larger ones by those turned by
<
lb

horses.</
