The bow and arrow are the weapons that used from the ancient time to the present. It has been developed within these centuries, and every ethnic group made its own specific bow and arrow and used that for hundreds of years. Same with this, Buryat-Mongols have made their own bow and arrow and used it to the naadam besides with the hunting. Same with other Mongol ethnics, the body of the Buryat bow and arrow is made from birch, and upper and bottom part of bow body or curved ends are made from horn, and the string is made from sinew. As mentioned in the report, it mostly made from the horn of a cow, but later it made from the horn of ibex, deer, and moose. The hide from the cow head was used in the making of glue, besides these glues were made from the fish and hoof of the cow.
