he course of these surveys, in order to the geographical
determination of the position of the line, the latitudes of 47 points
have been determined by means of 85 sets of altitudes of heavenly
bodies, and the sets of subsidiary observations for time and for the
determination of longitude by chronometers amount to 130. The number
of points at which observations have been made by barometers for the
purpose of determining their altitudes is 407, of which 267 are upon the
boundary claimed by the United States. The number of separate sets of
barometric readings made at these points amounts to 1,153, while those
made at the fixed stations amount to 837.

The division of Major Graham not having returned from the field
until within a few days, neither the reduction of the astronomical
observations nor any of the office work preparatory to a general map
has yet been commenced by his division.

The office work of the divisions of A. Talcott and J. Renwick has been
steadily carried on since the return of those commissioners from the
field in the month of October, and great progress has been made in the
calculations and plotting preparatory to the construction of maps, and
necessary as materials for a general report.

In this state of the work of the several divisions the undersigned find
themselves under the necessity of communicating to the State Department
that the further progress of their operations is about to be arrested by
the exhaustion of the appropriation, and of stating that unless speedy
provision be made for the supply of the necessary funds the report of
their operations can not be made up in time to be laid before Congress
at its present session.

The position of the finances of the commission may be seen by the
following statement:

Of the appropriation of $75,000 there have been drawn--

By J. Renwick $21,000
By A. Talcott 24,200
By J.D. Graham 25,000
Total drawn 70,200

Leaving in the Treasury of the United States $4,800.

By a careful estimate it is found that to finish the office work of the
several divisions there will be required over and above any balances in
the hands of the several commissioners--

For the division of J. Renwick $3,000
For the division of A. Talcott 5,800
For the division of J.D. Graham, including some
arrearages due for instruments and to assistant
engineers attached to this division
