the telescope. The
astronomical observations were therefore always made in the open air or
in a tent open to the heavens at top during the hours of observation,
and without a fire.
On the 16th of December the tents were struck and this party retired
from the field for the season, there being then more than 2 feet of snow
on the ground. To the unremitting zeal amidst severe exposures, and to
the scientific and practical attainments of the officers, both civil and
military, who served under the orders of the commissioner on this duty,
he acknowledges himself in a great measure indebted for the progress
that he was enabled to make, notwithstanding the many difficulties
encountered.
Observations were made during portions of three lunations of the transit
of the moon's bright limb and of such tabulated stars as differed but
little in right ascension and declination from the moon, in order to
obtain additional data to those furnished by chronometrical comparisons
with the meridian of Boston for computing the longitude of this meridian
line.
At the first station, 4,578 feet north of the monument, and also at the
Parks Hill station, the dip of the magnetic needle was ascertained by a
series of observations--in the one case upon two and in the other upon
three separate needles. The horizontal declination was also ascertained
at both these stations by a full set of observations upon six different
needles.
The details of these and of all the astronomical observations alluded to
will be prepared as soon as practicable for the use of the commission,
should they be required. To His Excellency Major-General Sir John
Harvey, K.C.B., lieutenant-governor of the Province of New Brunswick,
Major Graham acknowledges himself greatly indebted for having in the
most obliging manner extended to him-every facility within his power for
prosecuting the examinations. From Mr. Connell, of Woodstock, a member
of the colonial parliament, and from Lieutenant-Colonel Maclauchlan,
the British land agent, very kind attentions were received.
Major Graham has also great pleasure in acknowledging his obligations to
General Eustis, commandant of the Eastern Department; to Colonel Pierce,
commanding the garrison at Houlton, and to his officers; and also to
Major Ripley, of the Ordnance Department, commanding the arsenal at
Augusta, for the prompt and obliging manner in which they supplied many
articles useful to the prosecution of the labors of his
