marked on east side 54 and tied in two by two bearing trees, namely, 10 in. spruce 

 N. 15 degrees west — 0.17 chains and 5 in. Balsam S. 45 degrees west^O.076 

 chains. 



The hour being late and the distance to camp long and never doubting at 

 the time but that the latter post was due west of the 9 mile point, the markings 

 on the other post were neglected. So far we have been unable to get any light 

 on the matter. 



The meridiffli was then produced another 9 miles and from this point a 

 second east line run 9 miles with posts planted as per instructions, and a line 

 west to said O.L.S. Speight's line, a distance of 8 miles 75.73 chains intersecting 

 said line 0.49 chains south of XVIII mile post. 



The meridian was then produced 9 miles further and a third line run east 

 and west, the latter at VIII M. 73.73 chains intersecting the production of said 

 O.L.S. Speight's meridian 1.33 chains north of the XXVII mile post. 



Provisions by this time were running low, but we were able to run six 

 more miles of meridian before being forced to abandon the work within sight 

 of the goal. Had we been able to bring all the canoes along we would have 

 completed the contract but the one small canoe was capable of carrying only our 

 assistant and two canoemen to Fauquier on the T. C. Ey. over a route, the nature 

 of which we did not know, but which if navigable would prove the most con- 

 venient route by which to return to complete same or continue the outline work 

 farther north another year. With this idea in mind we had our assistant make a 

 compass survey of the route and have drafted same as per his notes on our returns 

 to your Department. 



Instrument Woek. 



A Light Mountain Gurley instrument was used on the work, and from two 

 to four observations taken every night that polaris was visible. These observations 

 were facilitated by the use of curves previously plotted in our office for the 

 latitude and longitude of the work, a copy of which we attach, and our watch 

 set for solar time and corrected every few days. 



We found observations solved by the use of this curve to check to the half 

 minute. 



Chainage. 



A chain of 400 links Avas used and the chainers cautioned not to break 

 chain but read the inclination with an Abney hand level and reduce to horizontal 

 distance, curves being also used for this purpose, a copy of which we attach. 

 The chainers were duly sworn in on the ground at the starting point, the chain 

 tested and re-checked twice during the survey, and we believe they strived hard 

 to render correct measurements. 



Elevations of all hills were solved from the inclination angles ts&en while 

 chaining. 



Posts and Bearing Trees. 



The most durable wood obtainable was selected and often carried many 

 chains and marked by a scribe, while the iron posts were marked with a cold 

 chisel. The largest trees were not selected for bearing trees but smaller and 

 more healthy ones which would not likely for some time fall a prey to the axe 

 of the lumberman, and these trees were chosen as far as possible in such a
