3. The division under the direction of J. Renwick has explored or surveyed the line of highlands from the southeastern extremity of Lake Matapediac to the vicinity of the river Du Loup, where the line of survey has been connected with that of A. Talcott. In this survey a gap is yet left of a few miles on the western side of the valley of the Rimouski near its source.
In the course of the operations of this division 586 miles have been passed over and such notes taken as will form the basis of a map. Of these 586 miles, 275 have been actually measured, 209 are upon the boundary claimed by the United States, and about 30 upon the line pointed out by the proclamation of the King of Great Britain of the 7th of October, 1763, as the southern boundary of the Province of Quebec, making in all 239 miles of the height of land.
In the 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.
