lation the distance to tliis point of intersection was measured with a 

 steel tape and was also checked liy stadia. 



It may he noted that no monuments were found niarkin;^ the inter- 

 national houndary near the point of its intersection with the Idaho- 

 Montana l)oundary line, and it is believed that there are lart;e sections 

 of this important line which are not marked and have never been 

 marked in any way. Considerable work was done by the Northwest- 

 ern Boundary Survey, but just how far this work pr()ceede<l is not 

 •known. The State Department, in answer to an inijuiry on the sul)- 

 ject, makes the statement that " The department lias no rejiort of the 

 western portion of the Northwestern Boundary Surve}' from the I'aeitic 

 Coast to the summit of tlie Rocky ^lountains.' It is suggested that 

 under these circumstances a commission similar to the one which 

 recently served in connection with the surve}' and remarking of the 

 boundary line Ijetween the United States and Mexico west of the Ilio 

 Grande might be a|)propriately appointed. There was fouml. how- 

 ever, among the I'ecords of tlie Northwestern Boundary Survey, in the 

 manuscript-room of the State Department, a list of jiositions deter- 

 mined, and in this list was given the position of the Mooyie Trail 

 monument, as follows: Latitude, 49° 00' 01.8"; longitude, 116^ 14' 

 59.2". This monument was identified on the ground about eight and 

 one-half miles west of the Idaho-Montana boundary line, and its posi- 

 tion determineil l)y triangulation with reference to the Spokane base 

 and astronomic jjosition as follows: Latitude, 49° 00' 01. ol" ; longi- 

 tude, 11(;° 14' 19.48". The check in latitude, 21 feet, was considered 

 very satisfactory, and even the discrepancy in longitude, al)out 2.(147 

 feet, was not more than might be e.\[)ected, considering the lack of 

 telegraphic facilities by the Northwestern Boundary Survey. 



The point determined as the true one for the intersection of the in- 

 ternational lK)undar\' and the Idaho-Montana boundary was located 

 with reference to tiie latitude of the Mooyie monument, so that there 

 may be no discrepancy wiien tiie international boundary is ultimately 

 traced and marked, it being assumed that the work already done by 

 tlie Northwestern Boundary Survey will be accepted and utilized. 

 The random line northward having been run, as previously statrd, 

 and the a<liustments jiaving been made fonneeting the line with tin- 

 triantrulation, the true line was then estalilisli<'d fiom iioith to .-(.iiih 

 ami the monuments were placed.
