The white stones are made of a kind of white shell; they are highly polished, and are exceedingly pleasant to the touch. The best come from the provinces of Hitachi and Mikawa. The black are made of stone, generally a kind of slate that comes from the Nachi cataract in Kishiu. As they are used they become almost jet-black, and they are also pleasant to the touch, but not so much so as the white. A good set is quite dear, and cannot be purchased under several yen. The ideograph formerly used for “Go ishi” indicates that originally they were made of wood, and not of stone, and the old Chinese ideograph shows that in that country they were wooden pieces painted black and white. The use of polished shell for the white stones was first introduced in the Ashikaga period.
In form the stones are disk-shaped, but not always exactly round, and are convex on both surfaces, so that they tremble slightly when placed on the board. They are about three-quarters of an inch in diameter, and about one-eighth of an inch in thickness. The white stones are generally a trifle larger than the black ones; for some strange reason those of both colors are a little bit wider than they should be in order to fit the board. Korschelt carefully measured the stones which he used, and found that the black were seventeen-sixteenths of the distance between the vertical lines on his board, and about eighteen-nineteenths of the distance between the horizontal lines, while the white stones were thirteen-twelfths of the distance between the vertical lines and thirty-six thirty-sevenths of the distance between the horizontal lines. I found about the same relation of size in the board and stones which I use.

The result of this is that the stones do not have quite room enough and lap over each other, and when the board is very full, they push each other out of place. To make matters still worse the Japanese are not very careful to put the stones exactly on the points of intersection, but place them carelessly, so that the board has an irregular appearance. It is probable that the unsymmetrical shape of the board and the irregularity of the size of the stones arise from the antipathy that the Japanese have to exact symmetry. At any rate, it is all calculated to break up the monotonous appearance which the board would have if the spaces were exactly square, and the stones were exactly round and fitted properly in their places.
In Japan the board is placed on the floor, and the players sit on the floor also, facing each other, as shown in the illustration, and generally the narrower side of the board is placed so as to face the players. Since the introduction of tables in Japan Go boards are also made thinner and without feet, but the game seems to lose some of its charm when the customs of the old Japan are departed from.
The Japanese always take the stone between the middle and index fingers, and not between the thumb and index finger as we are likely to do, and they place it on the board smartly and with great skill, so that it gives a cheerful sound, as before stated.
For use in this country the board need not be so thick, and need not, of course, have feet, but if it is attempted to play the game on cardboard, which has a dead sound as the stones are played, it is surprising how much the pleasure of the game is diminished. The author has found [[24]]that Casino chips are the best substitute for the Japanese stones.
