BRITISH NORTH AMERICAN EXPEDITION, [Nov. 23, 1857. 
Extract from Private Letter from Mr. Palliser, dated 21th July , 1857 : — 
“ I forgot to mention in my letter to Mr. Labouchere that the town which 
the Americans are about to build at our frontier line, is to be called St. Vincent. 
Mr. Iddings, the American engineer, told me, that as soon as he returns to St. 
Paul he will produce his map of the projected town and railway station, and 
they (the members of the Land Company) proceed to name the streets. I think 
I was just in time with my observation on the Boundary Line, and in coming 
to an understanding with the American engineer, which may perhaps be the 
means of avoiding unpleasant disputes hy-and-hye.” 
Note of Observations at Pembina by Captain Palliser, Mr. Iddings (U. S. 
Civil Engineer ), and Mr. Sullivan : — 
An observation taken at the above place by Mr. Nicolay (sic.) in 1848-49, 
places a post in latitude 49° n. 
An observation taken by Captain Palliser places the same post in latitude 
48° 59' 49" n. 
Mr. Iddings and my secretary, Mr. Sullivan, after ascertaining the variation 
of the compass, erected a second post distant from the first 870 yards due east, 
thus determining the direction of the Boundary Line.
