R.M. Brock 1957 Raising of youngs Litter 4 1 A.R.H. Barrow, Northern Alaska Aug 24 A new litter was found today in an aquarium which has had a pair of lemings in it since July 2 when a female was brought back from Pitt Point and placed in an aquarium with a male subadult caught at Barrow on June 24. At least three new born youngs were noted- being so young that the litter may not yet have been completely dropped. Aug 25 Today only a piece of one young one could be found. My mistake was probably in not removing the male right away because it was noted that the male was chasing the female about and that they were making moves as if they were not getting along. Also as mentioned yesterday, my disturbance was at a very critical time. End of Litter
