they obtained in checking between certain miles of the boundary and are 

 incorporated in the following table: 



Mile 3 to Mile 40: 



Plan chainage 2960 . 000 chains 



Our chainage 2967.240 " 



Geodetic triangulation 2966 .773 " 



Quebec township checks 2965.43 " 



Our chainage shows 7.24 chains more than the 37 miles in the original 

 survey or an average of 16.4 links per mile longer. 



In 37 miles, 23 mile-intervals fall between 80.09 and 80.23 chains, according 

 to our chainage. 



Two of the mile-intervals were found more than 81 chains, which look like 

 gross errors of 1 chain in each case. 



It would appear that the original survey was made with a short chain, 

 for 



1) failure to apply slope corrections would make the staked-out interval 

 shorter than recorded, and 



2) failure to apply temperature correction, even though it were always 

 30 below zero, would account for only 4.5 links per mile. 



The chainage of the part done in 1905 and of 2 miles of 1906 was as follows: 



Mile 40 to Mile 90: 



Plan chainage 4000.000 chains 



Our chainage 3996.597 " 



Geodetic triangulation 3994 . 270 " 



Our chainage shows 3.40 chains less than the 50 miles shown in the original 

 survey or an average of 6.8 links per mile shorter. 



In 50 miles, 30 mile-intervals fall between 80.00 and 79.85 chains according 

 to our chainage. 



One of the mile-intervals was 78.411 chains, a gross error of say 1.50 chains. 

 In this mile our main and check chainage agreed by .1 of a link but to make 

 doubly sure it was given another check which came within 1 link of first two. 



Monuments 



A monument was erected at every mile, either by renewal or reestablish- 

 ment. 



To Mile 42, the original monuments were of cut stone, at every mile being 

 made from stone near the line and planted during the winter. Nearly all of 

 them were found in place. The first three were completely lost, the fourth at 

 Mile 2 was found lying in a ditch, two others were found near their respective 

 corners but out of place and another was not found at all. 



From Mile 42 to Mile 89 the original monuments had been a 1%" hollow 

 iron pipe 3 feet long and a wooden post planted beside it, at every mile. Most 

 of these iron posts were found in fair shape, though the wooden post was often
