surprise to the inhabitants to learn peaches, apples, grapes, pears, rasp¬ 
berries, strawberries, and other fruits, can be cultivated with success. 
The discovery has given a wonderful impetus to this branch of enter¬ 
prise ; and, unless my judgment greatly misleads me, we shall hear of 
the Grand Traverse region, within ten years, as the fruit-orchard of 
the country; and shrewd men, with horticultural tastes and a moderate 
amount of means, will thank me for directing attention to this open 
avenue to wealth.

P. S. — Since the foregoing paper was read, I have been informed 
by Dr. I. A. fcqpham, of Milwaukie, that the themometer sank at that 
place only to —30° on the first of January, 1864. I have also received 
his chart of the summer and winter isothermal lines which cross Lake 
Michigan, showing that, the lake affects the climate very perceptibly, 
even in the region lying to the westward. In comparing the meteoro¬ 
logical means of Traverse City, therefore, with localities in Wisconsin 
and Minnesota, the contrasts, though well marked, are not so salient as 
if the comparisons had been made with localities quite removed from 
the interference of the great lakes. The windward position of Wis¬ 
consin, however, during our coldest storms, would prevent the extreme 
minima of the climate from receiving any alleviation from the prox¬ 
imity of the lake. 
2. STROMATOPORIDiE : THEIR STRUCTURE AND ZOOLOGICAL AF¬ 
FINITIES. By Prof. Alexander Winchell, of Ann Arbor, 
Michigan. 
A recent investigation of the organic remains of Little Traverse 
Bay, in the State of Michigan, has caused my attention to be directed 
to the nature and zoological relations of the Goldfussian genus Stroma- 
topora. Without attempting to present a synopsis of the literature of 
the subject, or even to enter upon a full discussion of the organic na¬ 
ture of the beings embraced under the genus, I desire to present a few 
suggestions, based on some interesting facts that have come under my 
observation. 
The genus Stromatopora was first briefly characterized by Goldfuss
