island clamor increased.

ducats to the crown and restricted the price at which the slaves were to
be sold in the islands to forty ducats each. In so far it approached the
asientos of the full type which became the regular recourse of the Spanish
government in the following centuries; but it fell short of the ultimate
plan by failing to bind the grantees to the performance of their
undertaking and by failing to specify the grades and the proportion of the
sexes among the slaves to be delivered. In short the crown's regard was
still directed more to the enrichment of courtiers than to the promotion of
prosperity in the islands.

After the expiration of the Eynger and Sayller grant the king left the
control of the slave trade to the regular imperial administrative boards,
which, rejecting all asiento overtures for half a century, maintained a
policy of granting licenses for competitive trade in return for payments
of eight or ten ducats per head until 1560, and of thirty ducats or more
