For present purposes the interesting features of this map are as 
follows : 
Opposite the eastern extreme of the Chukchi peninsula there is 
represented part of America with the legend, ‘‘Terres vues par Mr. 
Spanberg in 1728, frequentées a présent par les Russes, qui en apportent 
de trés belles fourrures.” In the English edition the legend is ‘‘Seen 
by Spanberg 1728.” Four islands are represented in the strait between 
Asia and America, corresponding in a general way to the four now 
known to exist there. Connected with America and north of the 
Chukchi peninsula is land with an island off it corresponding not badly 
to Wrangell and Herald Islands, and marked ‘‘ Discovered in 1722.” It 
is possible that this land is a hypothetical compound of the land 
reported by the Chukchis east of the strait with that which they knew 
to be visible in clear weather from Cape Yakan. more or less confused 
accounts of which had long been current among persons interested in 
these regions. ; 
The next chart of note in this connection was published by D’Anville, 
the royal geographer of France, who had previously prepared the 
original map of Bering for publication. He issued a general map of 
Asia, in three parts, each of two leaves which could be joined together, 
of which the first part appeared in 1751 and the third part in 1758, 
entitled :

quelques autres parties /de la Tartarie, / Publiée sous les Auspices

This map is in two sheets (each 20 x 21 inches), the engraving of the 
geographical part by Guill. de la Haye and of the ornamental title by 
De Lafosse. The longitude is reckoned from Ferro, and the map is 
constructed on a scale of 23 French leagues to 60 geographical miles. 
The boundaries are colored and the sea shore shaded with short hori- 
zontal lines. It is on the polyconic projection. 
This map includes many of the additions to geography in eastern 
Siberia which were due to the members of the great Siberian expedi- 
tion. The courses and branches of the rivers especially were aug- 
mented and corrected as well as named. The branches of the Anadyr 
River were represented and named, but as no new information in 
regard to the coast had been received at that date, this river was still 
mapped as entering the sea to the south and west of Cape Thaddeus, as 
erroneously laid down by Bering, who confounded with the Anadyr a 
small river which does come in here. and passed the estuary of the 
true Anadyr without seeing it. The coast lines are essentially those of 
Bering. Beyond the basins of the Kolyma and Anadyr is marked 
‘¢ Terre inconnue”; a small supplement in the north-east corner of the 
map, on half the scale of the map, represents the north-east extreme of 
Asia as delineated by Bering. This little supplement is of considerable 
interest as it gives fuller information than that which appears on the
