extended. In 1917 there were 28,827,000 m. of single wire in this
service as compared with 12,999,000 in 1907. The number of
employees nearly doubled during this period, increasing from
144,000 to 244,000. The Bell telephone system operated in 1919
23,281,000 m. of wire, of which 3,334,000 was for long-distance toll
service. The number of daily exchange messages of this system
alone was 30 millions and of toll messages one million. The
telegraph systems made but little extension between 1907 and 1917.
In the former year there were 239,646 m. of pole line and in the
latter year 241,012. The number of messages sent increased over
50%, from 101 millions to 155 millions; and the number of employees
from 26,827 to 49,608. (See Telegraph and Telephone.)

The automobile became an important factor in terminal transportation. Motor-car registration increased nine times between 1912 and 1920, numbering (not allowing for duplicate registration) in the latter year 9,211,295. This represents a motor car for approximately every 11 of the population. (See Motor Vehicles.)
Shipping.—Owing to the great activity in shipbuilding during the World War the tonnage of the American merchant marine showed a marked increase between 1910 and 1919, rising from 7,508,100 tons in 1910 to 16,324,000 tons in 1920. Nearly one-fifth, or 3,138,700 tons, was employed on the Great Lakes. The tonnage on the western rivers continued to decline, being only 120,230 tons in 1920. Sailing vessels decreased both in number and tonnage, and steam vessels declined in number from 12,452 to 8,103, but increased in size. The average tonnage of a steam vessel in 1910 was 394 tons, and in 1919, 1,359 tons. During the five years, 1910-4, the tonnage of new steam vessels built was 1,106,000 tons; and in the next five years ending in 1919, 4,948,400 tons, or more than four times as much. In 1920 new construction amounted to 3,880,639 tons. American shipping is engaged in two distinct branches of trade: coastwise trade between domestic points, and foreign trade. The tonnage in foreign trade increased from 1,076,152 tons in 1914 to 9,928,595 tons in 1920. Coasting tonnage remained about the same. It is estimated that the new tonnage, constructed under the emergency of the war, represented an expenditure of $3,000,000,000, a sum greater than the book value of all the world's merchant shipping in 1914, aggregating 49,000,000 tons. (See Shipping.)
A notable change has taken place in the nationality of shipping entering and clearing from American seaports. Until 1916 the tonnage of vessels sailing under foreign flags for many years was approximately three times as great as that under U.S. registry; in 1920 U.S. tonnage (26,242,332) equalled foreign tonnage (26,178,328).
The total tonnage of vessels entering at all ports from foreign countries increased from 40,235,800 tons in 1910 to 52,420,600 tons in 1920, and the tonnage cleared from 39,705,900 tons to 56,072,300 tons. The tonnage of British shipping entering at seaports of the United States fell from a maximum of 20,416,000 tons in 1914 to 11,237,000 tons in 1919. German tonnage entering in 1915 was 5,035,000 tons, and in the years 1916-9 was practically nil.
National Wealth.—In 1912 the Bureau of Census made an estimate of the wealth of the United States shown in Table 20, amounting to $187,700,000,000.
This gave an average of $1,965 for each person as compared with $1,165 in 1900. More than one-half the wealth consisted of real estate and improvement, largely due to the increase in value of urban real estate. In 1916 the value of taxable real estate in New York City alone was nearly $8,000,000,000.
Unofficial estimates of the national wealth have been made by statistical experts for dates later than 1912. That of W. R. Ingalls, of the U.S. Bureau of Mines, published in the Annalist, Sept. 13 1920, gives $216,600,000,000 for the year 1916. Other estimates run as high as $400,000,000,000. These figures, however, have little significance as evidence of domestic welfare. High prices increased appraised valuation; and high valuation, e.g. of real estate, may be a burden upon the productive efforts of the community.
The income-tax statistics published by the Commissioner of Internal Revenue throw light upon the distribution of wealth. In 1918 the number of personal income-tax returns was 4,425,114. The net income reported was $15,924,639,000; the tax collected on this income was $1,127,722,000; 34.3% of those making returns reported an income of from $1,000 to $2,000; 33.8% an income of $2,000 to $3,000; 21.1% an income from $3,000 to $5,000; and 7.2% an income of from $5,000 to $10,000. Incomes of $1,000,000 or more were reported by 67 persons. Of the total tax, New York state paid $354,000,000, or 31.4%; Pennsylvania, $138,000,000, or 12.2%; Illinois, $85,000,000, or 7.5%; and Massachusetts paid
