This table shows that while at times the minimum temperature 
is higher in the Central Highlands than at Fredericton or Chat- 
ham, it averages some nine degrees lower, and at times runs very 
much lower. The most conspicuous case of this is in the tem- 
perature 28° on the night of July 20-21. That this is no error 
of record or instrument is shown by the fact that in the morning 
we found outside our tent a cake of ice in the bottom of a cup, 
which was itself frozen to the moss on which it rested. I have 
noted another striking example of summer frosts in this region. 
On the sources of the Northwest Miramichi on August 27-2S, 
28-29, 29-30, 1903, the frosts were so heavy as to whiten all the 
vegetation around and freeze the water in our pails. Mr. M. I. 
Furbish has also sent me a note to the effect that once on August 
13th at the Waagan water froze in a pail beside his camp to such 
a thickness that the pail could be lifted by the dipper frozen in it ; 
and it is said there is frost there every month of the year, a
