[GANONG ] BOUNDARIES OF NEW BRUNSWICK 345 
Turning more directly to the surveys concerning New Brunswick, 
we find that in 1840 Major Graham proceeded to the monument at the 
source of the St. Croix and started to resurvey the due north line. He 
had the best of instruments and made very numerous astronomical obser- 
vations, and measurements of magnetic dip and variation, thus making 
a meridian line much more accurate than that run in 1817. The next 
year, 1841, he continued this line to the St. John and four miles beyond. 
He found that his new line at first ran to the westward of the old line, 
but later crossed it and reached the St. John about half a mile to the 
eastward of the line of 1817. The next year (1842) the line was con- 
tinued a few miles farther, to just south of Grand River, where it was 
finally terminated. In the meantime, in 1840, a preliminary explora- 
tion had been made of the watershed extending between the termina- 
tion of the north line and the Touladi, and the next year in 1841, this 
was thoroughly explored and surveyed, with careful lines of barometric 
levels, from east of the north line to Lake Temiscouata, with the ex- 
ception of a part of the watershed at the source of the Rimouski. The 
third year, 1842, a very careful survey was made of Green river, the 
original of our present maps, and of the portage to the Kedgewick, 
and the missing gap in the survey of the watershed south of the Ri- 
mouski was filled. In this year also the St. John from Grand Falls 
to the Alleguash, and the St. Francis, were surveyed, and careful deter- 
minations of the latitude and longitude of the mouths of the prin- 
cipal branches of the St. John were made. All of the work of this 
survey was of the very highest character, and in some respects was 
more detailed than that of the International boundary commission a 
few years later. The reports of the surveyors are of extreme interest 
to anyone who cares for narratives of life in the woods and exploration 
in this region. The data of this Renwick commission, including their: 
numerous lines of elevation, are embodied upon Graham’s map of 1843, 
published with the Third Report of the commission, and ‘reproduced 
by Moore, while the original maps upon which it is based appear to be 
preserved in the Department of State at Washington.” 

as Document 210 to occupy Vol. TX. of the House Executive Documents for 
1842-43, but it never appeared.. Richardson, however, in his ‘“ Messages and 
Papers of the Presidents,” Vol. IV., 234, publishes for the first time a part of 
their final report, all that he was able to discover in the archives at Washing- 
ton. Apparently, then, the invaluable observations for latitude, longitude, 
magnetic dip and variation, etc., have all been lost. 
1 In the years 1887, 1888, 1889, the United States Coast Survey connected 
the monument at the source of the St. Croix with the Coast by triangula- 
tion, and partially surveyed the St. Croix, as shown in the Reports for 1888- 
1891. The maps, however, have not been published.
