Planting, maturing, and yield of sabutan.—The plants from which the straw mats at Tanay are made are set out in plots near the houses of the workers. The suckers are planted in April at the beginning of the rainy season, and, while it is always stated that straw prepared from the leaves grown in the shade is best for weaving, yet the plants are never intentionally set out in the shade but are planted wherever an unoccupied plot of ground is obtainable. As a matter of fact, the patches to be seen in the sabutan towns grow in a semi-shade such as one would expect to find in yards where the usual ornamental and fruit trees and banana plants grow. Much of the sabutan is in the sun from morning to night; some is shaded during all or part of the day. The suckers mature leaves in the third year[9] but these are cut off and thrown away as useless and it is not until the fourth year that the lower leaves can be stripped into straw. Harvest takes place every four months, five or six leaves being obtained from a plant at each cutting. The plants are never irrigated but it is to be noted that the soil around Laguna de Bay is very moist and that the water table is close to the surface with a good seepage from the hills which are near the shore. It is probable that the plants differ in their production of leaves because some have many more branches than others and the climatic and soil conditions affect the yield.

Preparation of the straw.—The best straw is prepared during the dry season, because at this time there is sufficient sunshine to produce a good colored material. As a consequence the workers prepare a large quantity at that season and store it in or under their houses, wrapped in mats.

The leaves used are about 2 meters in length and 6 cm. in width. The central thorns on the back of the leaves are removed by cutting away the midrib. Two lengths about an inch in width are thus produced from which the outer rows of thorns may or may not be removed, according to custom. The lengths thus obtained are left in the sunshine and wind for about half a day to render them more flexible, after which they are cut into straws. For this purpose there is used an instrument consisting of a narrow wooden handle about 2½ cm. wide at the base, into which narrow sharp teeth, usually of steel, are set. Brass and even hard woods can be used for teeth. The point of the segment being cut off, the base is grasped in one hand, the inside of the segment being turned toward the operator. The comb-like instrument is forced into it about 4 cm. from the end of the base and the teeth are held against the first finger by pressure of the thumb. The leaf length is then drawn up by the other hand and is cut into straws depending in width upon the fineness of the comb used. If the leaves are too young they will break in this process. The stripped segments are then usually tied up into bundles as large around as the fist, and hung in some shaded place exposed to the wind. The length of time occupied by this process varies. In some places it is omitted, though it seems to be always carried out in Tanay. The bundles are then undone and the worker, holding the uncut base of each length in one hand, runs the straw between his fingers and the sharp edged ruler-like piece of bamboo held in the other. This is done several times and results in the removal of considerable moisture, the prevention of wrinkling, and greater pliability of the straw.

There are several variations in the processes followed for boiling sabutan. In the Province of Laguna a fistful of the stripped lengths with bases still attached are rolled up into a bundle and placed in fresh water in order to remove the coloring matter—in some places in clear, running river water, in other places in a can of clean, fresh water—for about twenty-four hours; the water is changed several times. In the last method the process is discontinued when the water remains clear. Bundles are then placed in cold vinegar, water or lemon water to which green tamarind fruit has been added to make the color of the straw lighter and to toughen it; the water is brought to a boil. Bamboo is used as fuel, as that fire is not so hot as a wood fire. The length of time required for cooking differs. One good authority states that it should be stopped when the odor of sabutan can no longer be detected in the vapor, which occurs after about fifteen minutes boiling. This authority also states that the straw should be removed when it takes on a reddish hue. Many women put the straw into clear boiling water to which nothing has been added. After this process the straw is allowed to cool, is washed several times in clean, fresh water and is spread in the sun to dry, whereupon it assumes a gray color. If there is no sun the cool straw must be kept in fresh water which is changed every twelve hours until the sun appears. If a greenish shade is obtained the process has not been correctly carried out. Straw from dark green, thick, old leaves, or from those grown in the sun, is often reddish brown in color.

The boiling processes noted are those used in the preparation of straw for mats. The process followed in Tanay has been described by Mr. Amado Simpoco, principal of the Tanay Central School. The stripped lengths, after being wilted and drawn over the sharp edged piece of bamboo, are made up into fist bundles, tied at the middle and placed in a large copper pot 61 cm. in diameter and 84 cm. in depth and containing about 25 bundles. The pot is filled with water and the sabutan is boiled for 24 hours, care being taken that the straw is always covered. After boiling, the bundles are removed and untied and the strips are hung in the shade or in the house to cool; afterwards they are placed in the river for a day and are then washed carefully and dried thoroughly in the sun. The gray straw thus obtained is stored in bundles, still attached to the uncut bases, and is left in the air for three or four nights before it is woven into mats.

Dyeing sabutan.—Mr. Simpoco has also made a careful study of the methods used in Tanay in dyeing sabutan straw, and the results of his efforts are presented here.

Red orange: For the production of red orange straw the gray material, prepared as outlined above, is first treated by steeping in water containing kolis leaves and twigs. The leaves and chopped twigs are pounded in a mortar and are placed together with the sabutan in a large receptacle capable of containing from 25 to 30 bundles, filled with water. The material is allowed to remain in the receptacle for four days. Early in the morning of the fifth day the straw is removed and hung in a shaded place until dry and is made up into bundles tied tightly at the larger end.
