The whole annual importation is derived from the following countries, and in the quantities given below, as near as one can approach to actual figures: Bombay and Zanzibar export 160 tons.
Alexandria and Malta 180 " West Coast of Africa 140 " Cape of Good Hope 50 " Mozambique 20 " The Bombay merchants collect ivory from all the southern countries of Asia, and the East Coast of Africa, and after selecting that which is most suited to the wants of the Indian and Chinese markets, ship the remainder to Europe.
From Alexandria and Malta we receive ivory collected from Northern and Central Africa, from Egypt, and the countries through which the Nile flows.
Immediately after the Franco-German war the value of ivory increased considerably; and when we look at the prices realized on large Zanzibar tusks at the public sales, we can well understand the motive power which drove the Arab ivory hunters further and further into the country from which the chief supply was derived when Dr.Livingstone met them.
In 1867 their price varied from L39 to L42.

Single tusks vary in weight from 1 lb.

to 165 lbs.: the average of a pair of tusks may be put at 28 lbs., and therefore 44,000 elephants, large and small, must be killed yearly to supply the ivory which _comes to England alone_, and when we remember that an enormous quantity goes to America, to India and China, for consumption there, and of which we have no account, some faint notion may be formed of the destruction that goes on amongst the herds of elephants.
Although naturalists distinguish only two living species of elephants, viz.

the African and the Asiatic, nevertheless there is a great difference in the size, character, and colour of their tusks, which may arise from variations in climate, soil, and food.
