502 Harlem River and Bronx Park the increase in land values due to the building of the subway was $31,300,000.

The report goes on to state that, while the increase in land values above 135th Street, due to the building of the subway, was $39,200,000, the cost of building the subway from this point to 230th Street was $7,375,000, or but 15 per cent of the actual rise caused by the new line. Similarly, the increase in the Bronx land values of more than thirty million dollars was caused by subway construction costing $5,700,000.

These instances are typical of the land value increases which are so apparent in New York City. Other great centers of population, however, show similar conditions. Mr. C. B. Fillebrown, in his "The A-B-C of Taxation," cites some interesting illustrations of increases in the land value of Boston. For example, the land values irrespective of improvements,

Similar illustrations might be cited in endless detail, showing the rise of land values in American cities. Even the casual observer must admit the very obvious facts of land value increase. The one thing needful is some accurate measure of their extent.

There are a few American cities in which a careful assessment of land independent of improvements has been made. In New York City, for example, the land and improvements have been separately assessed since 1906. The Report of the Commissioners of Taxes and Assessments for 1912 (pages 20-23) gives the land value assessments in considerable detail. The value of the land alone for Greater New York was, in 1906, 3,367 million dollars, and in 1912, 4,563 million dollars. This represents an increase in the per capita value of land from $811 in 1906 to $898 in 1912. Incidentally, the total value of all improvements in 1912 was only two billion, seven hundred and sixteen millions, or about three fifths of the total land value.

The boroughs separately show a considerable divergence in the ratio of increase. In the Borough of Manhattan, for example, the increase in
