20 NORTHWESTERN BOUNDARY OF UNITED STATES. [bull. 174. 
Second. There is a series of 19 sheets on tracing linen covering the 
entire line from the sea coast eastward to the Rocky Mountains. These 
sheets are numbered from west to east, 1 to 19. Each sheet except 
the first embraces 30' of longitude and from 15' to 25' of latitude. 
Sheet 2, for example, includes from 123° to 122° 30'; sheet 3, longitude 
122° 30' to 122°, while sheet 19, the easternmost of the series, includes 
longitude 114° 30' to 111°. The relief is shown by broken horizontal 
curves. The scale is not stated, but the parallels and meridians enable 
us to infer that it is 1: 64000, or about 1 mile to 1 inch. These sheets 
bear no title, no legend, no date, and no names. 
Third. There is a series of five manuscript maps (not numbered) on 
a scale of 1:120000, showing the entire line from the sea coast to the 
Rocky Mountains. They appear to be unfinished drafts. Relief is 
shown by contours in green, trails in red, and there are a few names. 
They are drawn on backed drawing paper. None of them have 
legends or titles, or names of draftsmen or any authority. They 
contain no dates. They appear to be compilations from original 
sketches, notes, and surveys. They are not numbered. Beginning 
at the west end of the line, the sheets cover the following areas: The 
first sheet covers from latitude 18° 40' to 49° 25', and from longitude 
123° 20' to 120° 50', being 30 inches high and 61 inches wide. The 
second sheet covers from latitude 48° 33' to 49° 35', and from longi- 
tude 121° 15' to 119° 12', being 38 inches high and 50 inches wide. 
The third sheet covers from latitude 48° 30' to 49° 18', and from lon- 
gitude 119° 35' to 117° 40', being 29 inches high and 50 inches wide. 
The fourth sheet covers from latitude 47° 35' to 49° 10', and from 
longitude 117° 50' to 114° 40', being 59 inches high and 55 inches wide. 
Owing to its inconvenient size this sheet has been cut into two pieces 
along the parallel of 48° 21'. The meridians are erroneously num- 
bered. The fifth sheet covers from latitude 48° 15' to 49° 35', and 
from longitude 116° 08' to 113° 13', being 50 inches high and 71 inches 
wide. This map also has been cut into two pieces along the meridian 
of 114° 55'. Like the preceding, the meridians are erroneously num- 
bered. Owing to its size, this roll of maps is not kept with the other 
material in the chests above mentioned. 
Fourth. There is an unfinished manuscript map, in two sheets, on 
unmounted drawing paper, covering the entire line from the sea coast 
to the Rocky Mountains. It includes latitude 47° to 50° and longi- 
tude 113° 30' to 125°, is on the conic projection, and is projected on 
the one hundred and nineteenth as the central meridian. The eastern 
part includes longitude 113° 30' to 119°, the western 119° to 125°. 
The scale is not stated, but appears to be 1 : 601000. There is no title, 
no date, no signature. It is an outline map, no relief being shown. 
The camps are shown, but the boundary monuments are not.
