NATURAL HISTORY AND PHYSIOGRAPHY OF NEW BRUNSWICK. 451 
51. — On a Lunar Rainboav Seen on Trowsers Lake. 
(Read Nov. 5, 1901.) 
The lunar rainbow is a not infrequent phenomenon, but a remark- 
ably perfect example, seen by Mr. M. I. Furbish and myself at 
Trowsers Lake on the evening of August 3rd, 1901, may be worth 
mention. About ten o’clock, a light shower with fleecy clouds came 
up opposite to the waning but bright moon, and against the clouds 
appeared a very perfect bow with the arch complete. No colors were 
visible, but instead the bow was of grayish light, not unlike the 
northern streamers. 
52. — On an Unusual Frost-effect of 1901 on the Tobique. 
(Read Nov. 5, 1901.) 
In the valley of the Tobique and elsewhere in central New 
Brunswick the firs and spruces in August last (1901) arrested atten- 
tion by the remarkable appearance of the tips of all their branches. 
The new growth of the year, from two to four inches in length, hung 
downward, brown, withered and dead. I was informed, no doubt 
correctly, that the destruction was caused by a severe frost during the 
first week in June. I noticed that many of them were sprouting 
again behind the dead part, and usually by two buds on opposite 
flanks of the branch. The growth of these trees for 1901, therefore, 
is likely to be marked for the future, both by its shortness, and also 
by the unusual amount of bifurcation in the branches, features which 
may puzzle the student unless he knows the true cause. 
53. — On a Hypsometric Section Across Central New Brunswick. 
(Read Nov. 5, 1901.) 
In August last, in company with Mr. M. I. Furbish, I crossed New 
Brunswick from the Tobique River to the mouth of the Miramichi, by 
way of Trow.sers, Long, Milnagek (Island), Little Southwest (Tuadook) 
Lakes, and the Little Southwest Miramichi River. Careful aneroid 
measurements* were made throughout the trip, after the methods and 
with the results described below. The great majority of the places 
mentioned have not hitherto been measured for elevation.
