The ice on the larger lakes in 
Lat. 66", Long. 114" completely 
broken up. About the 18th or 
19th of this month, the sea-ice at 
the mouth of the Coppermine 
River, in Lat. 67" 45', is sup- 
posed to have broken up. The 
Dryas integrifolia., Stellaria Ed- 
wardsii and Equisetum arvense^ 
flowered to-day. Epilobium spica- 
tum sending up young shoots.

In Lat. 68" on the coast, we had a 
severe storm this day, which, with 
frosty weather and snow, con- 
tinued for several days. The 
snow that fell at this time dis- 
appeared again, but on the 5th 
of September a storm set in, 
which clothed all the Barren 
Grounds from Lat. 65" to. 68" 
with snow for the winter. 
On the 9th of October, the party 
walked over the small lakes be- 
tween Point Lake and Fort En- 
terprize, which they had crossed 
on the ice in the middle of the 
preceding J une, being an interval 
of 116 days. The ground was 
this year covered with snow a 
month before the lakes froze 
over, so that the snow lay for 
nine months, and there were oc- 
casional snow-showers in the 
three summer months.
