They also employ the baths as a medicine, and God our Lord has given them for this purpose springs of hot water.  In the last few years the hot springs of Bai, on the banks of the lagoon of Bai, have been most healthful and famous, and many Spaniards of both sexes as well as ecclesiastics and religious, have had recourse to them in various maladies and recovered their health.  And, indeed, the ease and delightfulness of the trip almost compel one to undertake it, even though he may not need it.  The [Pasig] River extends inland as much as six leguas; and from its source in the lagoon until it reaches the bay of Manila, it is dotted with houses, gardens, and stock-farms, in most delightful variety.  As the trees in that climate bear leaves the whole year through, their verdure and coolness increase the charm.  I noticed but two trees which shed their leaves; both of them are wild, and do not bear fruit, but both are highly useful and valued for that reason.  One is the balete, [57] which grows very tall, has a round, cup-shaped head, like a moderately large walnut tree, and is of a most delightful green.  Its leaves are somewhat narrow, like those of the almond tree; and are hard, compact, and glossy to the touch, like those of the orange tree.  The Filipinos prize them for their use in cooking, as we do the laurel and the rosemary.  This tree is very hardy, and most often flourishes in rocky places; it has a natural tendency to produce roots over almost the whole surface of its trunk so that it appears to be covered with a beard.  The Chinese, who are really ingenious, are wont to plant one of these trees on a stone (so small that both the tree and stone can be held in the hand), just as if it were in a flower-pot, and then it can be carried from one place to another; and the tree, like a dwarfed orange tree, grows in proportion to its roots, hardly reaching five palmos in height.  As this method of planting these trees on a stone may seem as difficult as it is curious, I shall describe how I have seen it done.  They take a sprout of the tree when it is already covered with roots, and a stone which must not be too hard, or smooth, but not very solid, and somewhat porous or hollow.  These stones are found there in abundance among the reefs and shoals of the sea.  They tie the little tree or sprout to this stone, covering the latter so far as possible on all sides with the fibres and roots; and to make it grow, they cover the stone with water.  With the water the tree clings much more readily to the stone, entwines about it, and becomes grafted into all its pores and cavities, embracing it with remarkable amity and union.  A large balete stands in the patio [i.e., inner court] of our house in Manila, near the regular entrance.  In the year 1602, in the month of April or May, I saw it all withered, with its leaves falling.  Thinking that it was dying I was greatly grieved, for I did not wish to lose so fine a tree.  My sorrow was increased when I saw it next day almost without a leaf; and I showed it to our procurator, who chanced to be with me while I was inspecting the tree.  But on the third day I beheld it covered with new leaves, tender and beautiful, at which I was as rejoiced as I had previously been saddened; for it is in truth a beautiful tree.  In this I saw represented, as in a picture, the truth of the resurrection.
