or an average annual increase of a little less than 4 per cent in a
period of eighty-two years.

From 1860 to 1864 the increase was small, but from that year to the
end of Spanish domination the percentage of increase was larger than
in any of the preceding periods.

The treaty of Paris brought 894,302 souls under the protection of the
American flag. They consisted of 570,187 whites, 239,808 of mixed
race, and 75,824 negroes.

CHAPTER XXXIII

AGRICULTURE IN PUERTO RICO

After the cessation of the gold produce, when the colonists were
forced by necessity to dedicate themselves to agriculture, they met
with many adverse conditions:

The incursions of the Caribs, the hurricanes of 1530 and 1537, the
emigration to Peru and Mexico, the internal dissensions, and last, but
not least, the heavy taxes. The colonists had found the soil of Puerto
Rico admirably adapted to sugar-cane, which they brought from Santo
Domingo, where Columbus had introduced it on his second voyage, and
the nascent sugar industry was beginning to prosper and expand when a
royal decree imposing a heavy tax on sugar came to strangle it in its
birth. Bishop Bastidas called the Government's attention to the fact
in a letter dated March 20, 1544, in which he says: " ... The new tax
to be paid on sugar in this island, as ordained by your Majesty, will
still further reduce the number of mills, which have been diminishing
of late. Let this tax be suspended and the mills in course of
construction will be finished, while the erection of others will be
encouraged."

The prelate's efforts seem to have produced a favorable effect.
Treasurer Castellanos, in 1546, loaned 6,000 pesos for the
Government's account, to two colonists for the erection of two
sugar-cane mills. In 1548 Gregorio Santolaya built, in the
neighborhood of the capital, the first cane-mill turned by
water-power, and two mills moved by horse-power. Another water-power
mill was mounted in 1549 on the estate of Alonzo Perez Martel with the
assistance of 1,500 pesos lent by the king. Loans for the same purpose
continued to be made for years after.

But if the Government encouraged the sugar industry w
