=The Wool Product of the World.= From an interesting article on the wool trade of the Pacific coast, published in a recent number of the San Francisco _Journal of Commerce_, we learn that the number of sheep in the world is now estimated at from four hundred and eighty-four to six hundred millions, of which the United States has about 36,000,000, and Great Britain the same number. From 1801 to 1875 the wool clip of Great Britain and Ireland increased from 94,000,000 to 325,000,000 pounds. That of France has increased almost as rapidly, though the wool is finer, as a rule, and hence the superiority of French cloths. Australia produces nearly as much wool as the parent country--Great Britain. The United States product increased from very little at the beginning of the century to about 200,000,000 pounds at the present time. Of this California has produced about one fourth, and the Pacific coast as a whole almost one third. If the ratio of growth shown in the past prevails in the future, the day is not far distant when the Pacific coast will produce at least one half the wool produced in the United States, as not only California and Oregon, but also Washington, Idaho, Montana, Utah, and New Mexico are well adapted to its production. The wool clip of Australia is about 284,000,000 pounds; that of Buenos Ayres and the river Plata, 222,500,000 pounds; other countries not previously given, 463,000,000 pounds. The total clip of the world last year was about 1,497,500,000 pounds, worth $150,000,000. This when scoured would yield about 852,000,000 pounds of clean wool. * * * * * =Street Main Joints.=
