contains material illustrating the use of the horse among the 
Yakut. An important part of the subsistence of the tribe is 
mare’s milk, which is made into kumiss and into butter in large

served in large carved goblets. Butter-jars and large milk-pails 
are made of birch-bark. The Yakut canoe (top of Case 17) is 
similar in type to that of the Amur tribes exhibited in Hall 102.
