Greater economy of cost of construction is usually re-quired in an old, settled country than in a new and compara-tively unknown one. It was required to run a line on aportion of the Intercolonial from one point to another, a dis-tance of about three and one-half miles, as the crow flies,but over five miles by the reconnoissance route picked out,roughly, by the engineer. by the four roads, was mostly woods, and known to be almosta solid swamp. The instructions were to find a cross-country route, ifat all feasible, rather than the long round reconnoissanceroute which, if a long way round, was, however, feasible. The first thing we did was to run a traverse along theroad, as shown in the plan, taking levels as we went along ^,.e ^. The engineer had procured a fairly good map of thecountry, and with this map and provided with barometer,hand-level and compass, drove through the country in ahorse and buggy. From the point markgd starting pointOn the accompanying map he drove east along the roadabout two miles to where a road runs northwards towardsthe objective point. At the junction of those two roads wasvery high ground. To the left, that is the territory enclosed and also of setts every loo feet when we reached the higherground. This traverse we plotted in both plan and we proposed to run a line across through the swamp,starting at stat. g + 20, to ascertain the real nature of thecountry. It might not be as bad as expected. Off our plotwe took a bearing for our trial line across the swamp. .\swe went along with this line we found that, to our right, theSwamp ended a short distance from our tangent.
