Plate IV. Map of central Luzon, showing among other places, the localities 
chiefly referred to in this paper. 
Y. Upper figure. Under surface of leaf of anajao ( Livistona sp.). 
Lower figures. Outer surface (A) of a primitive type of salacot, 
made from anajao, with retaining strips of rattan. Inner surface 
(B) of same salacot, made of strips of bamboo, a few of them 
dyed; framework of wood. Actual diameter of salacot, 48 cm. 
VI. Upper figure. More highly developed type of salacot. Outer sur- 
face (A) of dyed strips of bamboo; body of anajao leaf; frame- 
work of rattan. Inner surface (B) of the same salacot, made 
of woven rattan with ribs of bamboo; the part intended to come 
into contact with the head made from bamboo over a rattan 
framework. Actual diameter of salacot, 36.5 cm. Lower . figure. 
Highly developed type of salacot. Outer surface (A) of nito ; 
body and framework of rattan. Inner surface ( B ) in the marginal 
half of the diameter made of quilted cotton, dyed; head-support 
of dyed bamboo, supported by similar strips of dyed bamboo 
attached to rattan. Actual diameter of salacot, 36 cm. 
VII. View in Pangasinan Province, showing buri palms ( A ) , and bamboo 
(B). 
VIII. Under surface of buri leaf. A marks the position of three of the 
numerous midribs, which are used for hat making, especially at 
Calasiao, Pototan, and Dumarao; B similarly indicates what is 
generally spoken of as buri-leaf, but really only the lamina ex- 
cluding the midribs, more widely used in the Philippines for hat 
making, mat making, and other similar purposes, than any other 
material; C is the petiole, within which are the fibro-vascular 
bundles, which are made into buntal. 
IX. Portions of hats, magnified 4 diameters, in order to show the weave, 
and differences in materials. In examining these figures, it is to 
be remembered, first, that the magnification implies that the 
strands appear coarser than their actual size, and secondly, that 
all of these materials are used in different grades of fineness. 
For these reasons, the prices are appended of the actual hats 
used for illustration. Upper left hand corner buntal (Lueban), 
6-peso grade; upper right hand corner, buntal (Baliuag), 10-peso 
grade; lower left hand corner, bamboo, 10-peso grade; lower right 
hand corner, buri-midrib (Calasiao), 8-peso grade. 
X. As in plate IX. Upper left hand corner, sabotan, 8-peso grade; 
upper right hand corner, Pandanus utilissimus, now usually 
known in Manila by the name balangot, 20-eentavo grade; lower 
left hand corner, ticog, 12-centavo grade; lower right hand corner, 
buri-leaf (Pampanga), 20-centavo grade. 
XI. To illustrate the double hat. Upper figure. Outer half (A) and 
inner half (B) of one buri-midrib (Calasiao) hat, complete except 
for joining together, and for the finishing processes. Lower figure. 
Calasiao hat, completed, 10-peso grade, actual diameter, 37 cm.
