George Bancroft to Viscount Palmerston.1Inclosure in last foregoing letter, July 31, 1848

Mr. Bancroft to Viscount Palmerston.¹

My Dear Lord: As your Lordship desired, I send for your inspection a traced copy, made for me at the Navy Department, of Wilkes’s Chart of the Straits of Juan de Fuca, Puget’s Sound, &c., &c. Unluckily, this copy does not extend quite so far north as the parallel of 49°; though it contains the wide entrance into the Straits of Arro, the channel through the middle of which the Boundary is to be continued.

The upper part of the Straits of Arro is laid down, though not on a large scale, in Wilkes’s map of *the Oregon Territory, of which I am sorry to say I have not a copy, but which may be found in the Atlas to the Narrative of the United States Exploring Expedition.[xxxvii]

I remain, &c.,
