6) — All crystals of classes "A", "B" and "C" destined for export
must
be packed in wooden cases with a capacity of 45 to 50 kilograms those
crystals in excess of one kilogram, being marked individually with
labels or tickets which denote the weight, class, the names of the
exporters, consignees and the number of the order.
7) — The classification and evaluation form for each lot must con-
tain the number of cases which form the lot, the number and classification of the crystals and names of exporter and consignee.
8) — "Lascas" may be shipped in wooden cases or appropriate bags.
Each
classification and evaluation form for "lascas" must contain the
quantity of bags or cases, types of "lasca" in each case or bag, export
value, source of product and the names of exporter and consignee.
9) — The exports of rock crystal will only be permitted through the

16. SALT
The
uses of salt are manifold and reach numerous industries in one form or
another but the principal may be considered to be the food and the
chemical alkali industries. In Brazil, by far the largest use is in the
former, within which there are myriad uses. The use in human
alimentation is well known. However, there is another which may well be
classified in this group, that of the preservation of foods which is
carried out to a relatively larger degree in Brazil than, for example,
in the United States where freezing is the customary method. Dried beef
(xarque) takes up large amounts of salt and is a carryover from former
days when it was the most practical method of conserving and
transporting meat. Pickling in brine is also quite common.
Salt
as a food for animals is another application for this mineral and in
Brazil, it is estimated that one head of cattle requires a normal
ration of 60 grams daily which for the total herd of Brazil
approximates 750,000 tons annually. For purposes of fattening the
ideal daily consumption rate is established as .being 80 to 150 grams
per cattle. Hogs normally require 30 to 60 grams, horses and mules 30
grams and sheep 1.5 to 2 grams.
Among
world producers, Brazil occupies tenth place in importance. The United
States is the largest producer and is followed by Russia and Germany.
In fourth place is China. The exports of Brazil are still of a small
magnitude as compared to the leaders Germany, China and Manchukuo and in
