It is a fact quite generally recognized by observers of the Indians that there is no custom more universal or more highly valued by the Indian than that of smoking. The pipe is his companion in council; through it he pledges his friends; and with his tomahawk it has its place by him in his grave as his companion in the happy hunting grounds beyond. It is, therefore, not strange that the pipe should be a type of their best handiwork. As stated by Catlin, the red pipe-stone from which all existing specimens of Indian pipes appear to have been made, was obtained from the Pipestone quarry in Minnesota on the dividing ridge between the St. Peters and Missouri Rivers. It was named Catlinite on account of its discovery by George Catlin, the eminent writer and artist, who made it the object of protracted research. Until recent years the quarries have been held as sacred and as neutral ground by the various tribes. It was there, according to Indian tradition, fully described in early records, that the Great Spirit called the Indian nations together and standing upon a precipice of the red pipe rock broke from its wall a piece from which he made a huge pipe. The spirit told them that they must use this rock for their pipes of peace, that it belonged to them all and that the war club must never be lifted on its ground. At the last whiff of his pipe the head of the spirit went into a great cloud, and the whole surface of the rock in a radius of several miles was melted and glazed. The legend, with others which, according to early records, have been treasured by the Indians, was taken by Longfellow to form the first picture in his _Hiawatha_. Silliman's _Journal of Science_ (Vol. XXXVII, page 394,) gives an analysis of Red Pipestone. It is pronounced to be a mineral compound (and not steatite), is harder than gypsum, and softer than carbonate of lime. Specimens bear as high a luster and polish as melted glass. It may be of interest to the reader to know more of the ends sought by these treaties, also more concerning the contracting parties. In separate treaties, all of the same tenor and made in October, 1865, with various tribes of Sioux, those Indians promised to be very good and to maintain peaceful relations with the whites. In consideration therefor the U. S. Government promised to pay to each family or lodge the sum of $25.00, payable annually for a stated period, also to distribute to the widow and the seventeen children of Ish-tah-cha-ne-aha the sum of five hundred dollars, said friendly chief having been slain by U. S. soldiers. To one of these instruments were affixed the signatures of the following eminent warriors, whose names are given in the form in which they appeared on one of the documents,--the translation also being written as shown.
