Upon iny arrival, in 1895, I impressed upon Mr. Grebuitski the desirability of 
liaviug' sucli a census prepared, and suggested that Selivauof, the kossak in cliarge of 
the rookery, be ordered to undertake the work. Mr. Grebuitski, fnlly aware of the 
great importance of knowing exactly what classes were represented in each drive, at 
once took irp the suggestion and ordered Selivanof to make a detailed tally of each 
drive according to the scheme I furnished. The drive on July 19 I counted myself 
conjointly with Selivanof, and the tally sheet is here produced to show how the work was 
done and how much reliability can be placed upon it. The seals killed and those escap- 
ing from each pod, as it was culled and slaughtered, were separately counted, Feoktist 
Ivanof Korsakovski counting the dead ones, Selivanof and I those allowed to escape.

The accuracy of the above tally is attested by the fact that the number of skins 
taken in this drive was 515. Sometimes the killed ones of the previous pod were 
lying so close to those being counted that it was difficult to ascertain the exact number, 
in which case the smaller figure was noted. And so with the escaping ones. Selivanof 
and I counted separately; if we differed, and a recount was not practicable, we took
