182 The American Geologist. September, 1903. 
Only by following rational methods, can truthful results 
be expected in topographic modelling. Data must be gathered 
in the field under expert direction and be embodied into the 
work by a scientific system. This requires the supervision of a 
qualified geographer. 
Forms must be characteristically expressed, truthfully rend- 
ered and consistently colored. This calls for a specially trained 
landscape sculptor and colorist. 
NEPHELINE SYENITE IN WESTERN ONTARIO. 
By Willet G. Miller. 
Last summer the writer found several boulders of nephe 
line syenite, a couple of feet or so in diameter, not far from 
the east shore of the upper part of Sturgeon lake. This 
locality, by the canoe route, is about 75 miles northward of 
Ignace station, on the Canadian Pacific railway. Syenite 
somewhat similar in character, but in which no nepheline 
was observed in hand specimens, was seen in place on the 
shore of what the prospectors call Nine-mile lake, on the 
route from the northeast arm of Sturgeon lake to Savant 
lake. This outcrop was not carefully examined. It is ex- 
tremely likely, however, that the nepheline syenite is in place 
in the district lying between the two lakes, judging from the 
character of the outcrop seen, and from the fact that bould- 
ers of nepheline-bearing rock are somewhat abundant some 
miles to the southward. 
The interest in the finding of these boulders, 150 miles 
northwest of Port Arthur, lies in the fact that they show 
nepheline syenite to exist farther to the northwest than had 
previously been known to be the case. The occurrences of 
this rock, which was formerly placed among the rare varie- 
ties, in Hastings county and adjoining territory in the most 
eastern part of the Province, as well as across the Ottawa 
river in ucDec < at lake Kippewa and other points, and along 
the north shore of lake Superior in the vicinity of Port Cold- 
well, have been described in the last three or four volumes 
of the Bureau of Mines. A unique type of nepheline-hold- 
ing rock has also been described from the southeastern part 
of the Rainy River district, bv Dr. A. C. Lawson. It is thus
