it be the excrement or vomit of whales, or a reaba which the
sea produces in its depths. But in Jolo it is apt to be more often
found, because those islands are scattered and their coasts prolonged
for many leguas opposite many currents and channel-mouths. And for
this reason some amber is usually found in Capul, an island beaten by
so many currents--as the ships which come on the return from Nueva
Espana know by experience--and also in Guiguan and on the beaches
of Antique. Near Punta de Naso the sea cast up, in the year 1650,
an enormous piece of amber, although it had not the fine quality and
excellence of that which comes from Japon. (Diaz's Conquistas, p. 447.)

[For several years after Corcuera's expedition against the Mindanaos
(1637), various military operations were conducted in that island
by the Spanish forces, notably under Pedro de Almonte. Corralat and
other Moro chiefs were sufficiently reduced to render them nominally
peaceful; but they formed various plots and conspiracies against the
Spaniards, and, on the other hand, these availed themselves of the
jealousies and personal interests of the Mindanao chiefs to separate
them and neutralize their efforts. The foolish arrogance of a Spanish
officer, Matias de Marmolejo, caused an attack on his detachment by
Corralat and Manaquior; all the Spaniards save Marmolejo and six
others were slain (June 1, 1642), including the Jesuit Bartolome
Sanchez, and the survivors were captured by Corralat. But when
Corcuera heard of this encounter he was so angry that he ordered
Marmolejo to be ransomed and afterwards to be beheaded in the plaza
at Zamboanga, for disobedience to his orders. He also ordered that
the fort at La Sabanilla be demolished, and the men there be sent
to punish Corralat, which was done. That chief, to revenge himself,
intrigued with the people of Basilan to secure possession of the
Spanish fort there; but its little garrison defended it against the
Moro fleet until aid could be sent them from Zamboanga. As soon as
Diego Fajardo became governor of the Philippines in Corcuera's place,
he endeavored to secure peace in Mindanao, and finally (June 24,
1645) a treaty of peace was signed by Corralat and his leading chiefs,
and Francisco de Atienza and the Jesuit Alejandro Lopez. This treaty
settled questions of mutual alliance, of boundaries of possessions,
of trade, of ransom of captives, and of freedom for the ministrations
of Jesuit missionaries. Christi
