POTTERY
As a tribe the Pimas are not skillful potters. Their work is decidedly inferior to that of the Kwahadkʽs, which in turn appears to be improving as a result of a moderm demand for it. It is probable that the best potters among the Pimas are of Kwahadkʽ descent, or have learned the art from that tribe. A great part of the Pima ceramic ware is plain and undecorated. The cooling ollas in which water is kept about their homes are the only vessels that are generally decorated. The potters aver that the designs are copied from the Hohokam potsherds that bestrew the mesas and that the symbolism is absolutely unknown to them. Furthermore, many of the smaller decorated pieces are traded from both the Kwahadkʽs and the Papagos, the . latter bringing them filled with cactus sirup to exchange for grain. The vessels here illustrated were made by Sala Hina (fig. 51), one of the best potters on the Gila.
Material
The common ware that is intended to be subjected to heat is generally made from clay obtained among the Skâsŏwalĭk hills, which lie on the southern border of the Gila River reservation. The material is a dry
granular clay combined with quartz pebbles and feldspathic detritus. The place where it occurs looks much more like a stone quarry than like a clay pit (pl. XVI, a). Indeed, a great part of the mass is sharp, angular stone, which must be winnowed out by hand in the shallow baskets.The process is well illustrated in plate XVI, b.[1]
Another well-known clay pit is situated on MeClellen's branch, at the northeastern base of the Sacaton hills (pl. XVI, c), whence a whitish clay is obtained. The villages about the Casa Blanca ruin obtain clay from pits within a stone's throw of the ruin itself and from the river bottom near the village of Rso’tûk.
The tempering materials used in the clays last mentioned are sand and ground potsherds. The clay from the Skâsŏwalĭk hills is so coarse that it requires no tempering.
Red ocher is employed as a slip, which is applied to the surface of the common utensils just before the drying that precedes burning. The water coolers are usually made without this coating of ocher.
Black gum is used for decoration. This is obtained by boiling in a small earthen pot, or in a segment of a large one, mesquite chips from portions of the tree on which black gum has dried into hard scales. After boiling, this dye is in the form of a very thin liquid which is so pale that it is scarcely distinguishable on the dark clay, but after the vessel has been given a sight burning the pattern appears in deep black.
Implements
As the new vessel is built up the outside is struck with a paddle (pl. XVII, b), and the inside is supported by a flat circular stone about 10 cm. in diameter. A smaller stone is used to polish the outer surfaces. Long, smooth, finger-shaped stones are used in polishing the necks of vessels or in places where there are sharp curves.
Method
The fictile ware of the Pimas is made by coiling. The clay is first thoroughly dried, a condition that is easily and quickly brought about by spreading it on blankets in the sun. It is then sifted to remove the larger particles of stone. It is next mixed with water and kneaded a few minutes, formed into lumps the size of the fist, and laid aside to "ripen" over night. The base of the new vessel is begun by spreading a layer of clay over the bottom of an old vessel of suitable size and smoothing it down with the paddle until it extends out several centimeters from the center (see pl. XVII, a, where the vessel shown in the potter's lap has just been taken from the olla over which it was molded). The new bottom is allowed to dry an hour in the sun before it is removed and the process of coiling begun. Dipping the fingers in water, the operator moistens the edges of the new vessel, which has dried enough to retain its shape. Then taking one of the prepared balls of clay she rapidly rolls it between the palms until it is lengthened into a cylinder about 20 cm. long, which is laid on the margin of the vessel and pinched into shape. One or perhaps two more rolls are laid on to complete the circuit and then the paddle is applied with the right hand in quick taps to the outside while the circular stone is held on the inside with the left (pl. XVII, b). The handle of the paddle is held downward so that the transverse concavity of the instrument is adapted to the horizontal convexity of the growing vessel, which is held in the lap and the coils applied only so fast as they dry sufficiently to cause it to hold its shape. For this reason it is customary for a potter to model three or four vessels at the same time so there need be no delay by waiting for the last layer to dry. As each coil is finished it is placed where the sun can shine upon it and the work progresses much faster than it could in a less arid climate. As soon as the vessel has been built up a little way so there is room for the paddle to be used above the plane of the bottom it is placed on the ground and a little loose soil is drawn up to serve as a support and in this it is turned slowly with the hands as required (pl. XVII, c). As the lower coils become dry they are smoothed with a polishing stone with strokes made from below upward; if a part has become too hard to be easily rubbed down the hand is dipped into the vessel of water that is within reach, and applied to the spot.
When the last coil has been shaped a dark red shale is ground in water until the liquid has become quite thick; this is applied to the outer surface with the hands. As the slip dries it is rubbed with the polishing stone until it becomes hard and smooth.
After drying over night the vessel is ready for burning. A very shallow pit is dug and a fire is kept in it for some time to dry the earth thoroughly, then a little dry mesquite or decayed willow wood is spread in the depression, and the vessel is laid on its side upon the wood and entirely covered with sticks laid up "log-cabin fashion." In the specimen shown in figure 52 the wood had burned away in about twenty minutes. The photograph was taken as the burning brands fell from the sides.
The final step, if the vessel is to be decorated, is to apply the black mesquite pigment with a sharpened stick (pl. XVII, d), made from Baccharis glutenosa, which has a large pithy center. The vessel is again subjected to heat for a few minutes until the decoration has assumed a deep black color, when it is finished.
Finished Products
Water reservoirs or coolers (fig. 53, a, b) are the largest and finest pieces of fictile ware made by the Pimas and Papagos. The latter carry on a thriving trade with the whites by supplying each house with one or more of these big round-bottomed pots, which are so porous that the evaporation from the outside measurably cools the water within, Although the term "olla" is applied to all Indian pottery in the Southwest, the word generally refers to this particular class of vessels. One will be found set in a three-forked post under the arbor at every Pima home.[2] An olla was secured which had been hidden away among the rocks in the hills for many years (fig. 54). It is among the smallest of those used for water coolers, and may well serve here to illustrate the minimum size and also a variation in decoration.[3]
Ollas with angular profile are not uncommon (fig. 55).
Cooking pots (pl. XVIII, a) are more numerous than the water coolers. Every kitchen contains several; some of them broken in halves or smaller fragments, yet retained for use in parching wheat or corn over the fire, or for other purposes. They are undecorated and not carefully smoothed and polished "because they would be slippery to handle when they became wet."[4]
Bean pots are made with handles as represented in pl. XVIII, b. They form a distinct type unlike any other aboriginal ware known to the writer.[5]
Canteens were formerly made of pottery, but they have been superseded by the cheap and scarcely less fragile metal ones of American manufacture. They were globular in form, and not provided with projections or loops for the attachment of straps. In fact, they were intended to be carried in the woman's kiâhâ; men on the warpath or traveling far from water must learn to endure thirst, but the women when compelled to go far for wood or cactus fruit were accustomed to carry water in these canteens. The vessels were sometimes broken, and Sala Hina told us of such an experience in which she nearly perished of thirst before she reached the river, though she had gone but a few miles from home. Canteens were decorated in a variety of patterns, including human figures.[6]
What may be termed a parching pan (pl. XIX, a) is made for roasting grains preparatory to grinding them for pinole. It is a large oval shallow dish with margin extended at ends for handles.[7]
A tortilla baking plate (pl. XIX, b) is sometimes seen. It is nothing more than a slightly concave undecorated disk.[8]
Cups were seldom made of clay; dippers of gourd or bowls of basketry were lighter and less perishable. It is probable that most of the few cups of Indian manufacture now to be found among the Pimas were obtained from the Kwahadkʽs or the Papagos. They are so highly polished as to appear to be glazed and are usually decorated with geometric designs to which no meaning can be ascribed by their makers.[9]Plates (pl. XIX, c, f) are now obtained from the Kwahadkʽs, but it is doubtful if the latter made them before the advent of the whites. They are polished and decorated in a manner similar to the cups.[10]
Fanciful figures of a variety of shapes are made by the Kwahadkʽs in imitation of American crockery, and the like, and are traded to the Pimas, who sometimes sell to gratify the desires of tourists for souvenirs, the seller being as ignorant of the fact that the buyer wishes to get specimens of Pima handiwork as the latter is of the fact that the ware is packed on the heads of women from the villages of another tribe 30 to 50 miles to the southward.
Two specimens (pl. XIX, d) were obtained from a Pima woman at Casa Blanca, who had "made them to sell," which have not the characteristic polish and the decoration of Kwahadkʽ ware. They are of interest because they show the Pima method of treatment of the human figure in clay modeling, and also the manner in which the face was painted. The larger effigy[11] has light brown lines on the body, both front and back, which represent a necklace, belt, skirt (perhaps), and what would seem to be the V-shaped opening at the neck of an upper garment. The face is painted in vertical stripes of red and blue, as was the custom with this tribe a few years ago. The front hair is represented on the forehead by prominent ridges.
The smaller effigy[12] has fewer lines on the face, and the body is undecorated.
From the ruins pottery spoons or ladles are sometimes taken which have apparently acquired magic import from the character of their source. These spoons are used in feeding the sick, and for no other purpose, so far as the writer is aware. The collection contains one very old spoon of Pima manufacture,[13] which is practically an elongated bowl (pl. XX, a). Another specimen[14] was made for us to illustrate the type, which, though rare, is well recognized (pl. XX, b). The collection contains also a bowl (pl. XX, c), two coiled bowls (pl. XX, d), and two decorated bowls (pl. XX, e).
Pottery was mended with gum from the creosote bush, Larrea mexicana (pl. IX, a). This bush grows abundantly on the driest plains of the Gila watershed, but its leaves are so bitter that it is not touched by stock, however extreme may be their hunger.

For industrial purposes an attempt is made to separate the proximate constituents of a clay by what is called a "rational analysis." For this purpose the clay is treated with sulphuric acid, which is supposed to dissolve the clay substance proper and leave insoluble quartz sand and sand composed of feldspar or other minerals.
In order that the composition of this clay might be compared with analyses of other clays made upon this plan, a determination was made of the matter insoluble in sulphuric acid in sample 24881, with the following results:
