572 to 1900 was at the rate of 3.45 per decade. Should this decrease continue the percentage of increase would cease in 1950 and thereafter a decrease in population would ensue. The population of the country would then be 88 millions in 1910, 101 millions in 1920, 111 millions in 1930, 119 millions in 1940 and 123 millions in 1950, at which time the population of the country would have reached its maximum and would thereafter decline. It is of course unlikely that this will be the future of our population. The percentage of increase will almost certainly become smaller, but probably with increasing slowness. The data from 1860 to 1900, however, give indications of these results, and they are more probable than the boundless increase of population of the country and of the world which has sometimes been predicted.

gifts to educational institutions the following may be noted: Princeton University has received from donors whose names are for the present withheld a gift of $1,200,000, for the erection and endowment of two scientific buildings—one for physical science and one for biology and geology. In each case the building will be erected as a cost of $400,000, and $200,000 is provided for equipment and maintenance.—By the will of Edward W. Currier Amherst College receives the sum of $500,000.
