grouping by these weapons, a separation of forms according to specific marks of structure, is possible for the study of the tribes. The feathering, which seems to be capable of unlimited variation, is of great importance. A great deal of care may be bestowed on the fastening of the feather, on the wrapping of the shaft with thread, or upon the manner of fitting the feather. The wrapping of the feathered end or shaftment offers excellent opportunity to preserve certain textile patterns, perhaps the one remaining survival of the old tribal peculiarity. The fastening of the point to the shaft or to the foreshaft also affords a safe datum for discriminating, and the shape of the point furnishes a guide for differentiations.
An Aztec Pictorial Record.—The forty-four paintings of the Mapa de Cuauhtlantzinco were executed in oil colors on European paper by an artist named Tepozetecatl, and are of high importance in the history of the conquest of Mexico. The Pueblo of San Juan de Cuauhtlantzinco, to which they belong, is situated between the cities of Pueblo and Cholula, and is inhabited by about fifteen hundred people, who still speak the Aztec language. The pictures, each about sixteen by twelve inches in size, were discovered about thirty years ago by Padre D. José Vicente Campos, who, to save them from decay, had them pasted on cotton sheeting and mounted in two frames. They contain scenes from the conquest—not badly executed—and portraits of aborigines. Each bears a text in Nahuatl, which Padre Campos translated into Spanish and appended the translation to the original. Another series of ancient paintings somewhat like these was preserved for a long time at Tlaxcala, but, according to Prof. Frederick Starr, they were less personal and less local. They are called the Lienzo de Tlaxcala, and picture all the important events of conquest from the time when Cortes came into contact with the Tlascalans till the city of Mexico was captured. The Mapa de Cuauhtlantzinco deals with but little space; perhaps Texculco and Chalco and Quimistlan describe its limits. The pictures and the texts in Spanish and English have been copied by Professor Starr, who publishes them for their ethnological interest, in that they illustrate a practice, common at the time of the conquest, of painting representations of important matters; that they in many cases present successful portraits; that they are, in conception and execution, truly native works of art; that they give considerable information relative to daily life and customs; and that they are psychically interesting in showing the feelings of the natives shortly after the conquest toward their conquerors and toward the newly introduced religion. The town of Cuauhtlantzinco appears to have been settled between 1519 and 1528 by refugees from Cholula, who were driven away because they had gone to Tlaxcala to visit Cortes and invite him to come to their pueblo.
Permanence of the Fish Supply.—A Scottish fish commission has been for fifteen years conducting an experimental research on the capacity of the sea to bear the drain upon its resources made by the growing industry of trawl fishing along shore. Some first-ciass fishing grounds along the coast were closed for several years, in the anticipation that the fish, freed from molestation, would breed and multiply in them. The conclusion reached from examination of the results has been that fishing or no fishing makes no difference whatever. "On the preserved grounds there are no more fish, and no less, than when the trawls were daily dragged across the bottoms of the bays. For the rest of the areas frequented by trawlers beyond the three-mile limit the happy conclusion is that there are as many fish in the sea as ever, and that the supply does not diminish, in spite of the increased and increasing number of ships engaged in the fisheries and their fine equipment." The equipment of steam trawlers for the North Sea and the open ocean has become an immense industry in the east of England. Never have so much capital and labor been spent in harrying the fish since the fishing began. "Yet the take steadily increases as the boats increase. 'The great labor and expenditure of the last ten years prove that the balance of Nature in the neighboring seas is steadily maintained, and that there is no need for anxiety concerning the continuance of every species of good fish.'. . . . It is now clear that life in the sea is not de-
