26 TREES AND TREE-PLANTING. 
There are about forty mills engaged in cutting red- 
wood, the largest of which have a capacity of 75,000 or 
80,000 feet per day. Perhaps the average working ca- 
pacity of all the mills would be about 40,000 feet daily. 
The amount of redwood sawed by these mills in 1881 
was not far from 140,000,000 feet. Of this, 95,000,000 
came to the port of San Francisco ; the balance, 45,000,000 
feet, manufactured, was distributed to the lower ports 
in California, Mexico, South America, Sandwich Islands, 
Society Islands, and Australia, vessels going direct from 
the mills. Very few vessels, however, run all the year 
round, both on account of the difficulty of keeping them 
supplied with logs, and because the places where many 
are situated are not safe harbors for shipping in winter. 
As very few of the mills are connected with the market 
by rail, nearly all the lumber is transported by sailing- 
vessels.
