Each of these large houses is surrounded by a number of rat-rafts which are like outlying fortresses of the great central. â â â ylitn Fio.

Their first purpose seems to be furnishing the members with landing places where they can feed comfortably; but when the ice forms they answer a new needâthey afford breathing places; for the reed raft makes it easy to keep the ice open there, and also conceals thr Musk- rat that is using the place. In the winter, if the occupants be frightened out of the big citadel, they will usually be found in a few minutes scattered at the various breathing raft-holes. In very deep water we find a type of nest that is both house and raft. Its foundation instead of being a mud island is a float- ing mass of reeds. It answers well for the fall and winter, but usually becomes water-logged and sinks from sight in the spring. li qp / t< HJ'JH.
