ig great. Systematic exploration of the areas of less abrupt topography, lying
between the exposed sections, may reveal commercial deposits, but such explora-
tion would be expensive. “ Therefore, in view of the more favourable conditions
under which bituminous sand is found elsewhere in the MeMlurray district, it
is doubtful if, with one or two possible exceptions, the deposits referred to in
Section No. 1 (between Boiler rapid and McMurray), should be seriously con-
sidered at the present time.”

Along the Athabaska, north of McMurray, thirteen of the more promising
outcrops were examined in some detail. “ Although all are outcrops of what
is apparently one continuous deposit, there is, as elsewhere, considerable varia-
tion in quality of material, and mode of occurrence. Consequently it is probable
that of the thirteen outcrops examined, quite 50 per cent may, for the present,
be eliminated from further consideration. The table on page 90 indicates
measurements of representative sections, and requires no comment.”
