‘New Haven, March 31, 
Arr. XI.— Table showing the First Appearance of Ice, the Clos-

To the Editors of the American Journal of Science and Arts. 
GentTLEMEN—The annexed table is submitted to your examina- 
tion, and if considered of sufficient value to be entitled to a place 
in the Journal of Science and Arts, I shall be happy to see it in 
print. Ihave thought this table might not be without its inter- 
est to those engaged in the navigation of the Connecticut river, 
as it will furnish them with data for sixty years, of the closing 
with ice, and the periods of opening at Middletown, situated 
thirty miles from its mouth. Iam not aware that any similar 
table relating to the Connecticut river, has ever been given to the 
public. The Regents of the University of the State of New 
York, have considered the “periods when the Hudson river is 
opened and closed at Albany,” of sufficient importance to be 
printed in their annual reports, made to the legislature of that 
State, see Document No. 56, p. 206, for 1839. The dates there 
referred to, commence in 1786, but the table is incomplete till 
the year 1818, when the opening as well as the period of the 
closing of the Hudson river, is given. ‘This table may also be 
serviceable to the geographer desirous of ascertaining the periods 
great rivers of North America continue icecbounds and for 
‘comparison with the rivers and climate of the north of Europe.
