By J. ^^r. tyiay) it was found a short time a^^o, wiien tin; (luestuju r s (M'dcrs, ami, alon^,' with tlu' ri!st of our oiitiit, siir.Jfigkid aboard our l»oat his l^c iniiij^loii rillc A boat's compass, a prismatic and a patent lo^', were, as usual, our survi^yinj,' instrunu'nts. and we pioc.eeded from point to point takinj,' our be.'iriugs and mcasuriu},' tlie distance in the usual way. When we hail traversed a short distance--not more th.in two miles— aloii},' the north shore of the outer island, and wen- about to enter a little rove in the shore, our attention was diverted by the api)earanc(.', a few yards ahead of us, of two polars swimminf; in the wat(;r — a larj^'i; she i)ear and her cub. They did not appear to take mucli notice of us until we },'ot between them and tlu; shore, hoping to cut off their escape by land. But thuigs did not seem to work that way, for the old bear, seeing our move, headed for the boat and in a moment dis- appeared below the water. Our rifleman had taken up his position at the bow of the boat, and the writer, having along with him a 38 cal. S. & VV. revolver, took a position beside him and waited for the reajipearance' of the i)ear. Presently she appeared, but at the stern of the l)oat, wlu^re the doctor was seated steering, and immediately she procc;eded to climb in. We in the bow dare not fire as two sailors and the doctor were standing in front of us ; but some way or other, through the assistance of a pike pole and the motion of the boat — for besides it being inider con- siderable headway, the water at the time was very rough — we man- aged to part with our new acquaintance. It was about here that the track surveying proper came in. Several parting shots were firetl as the bears were swimmmg ashore, and afterwards as we saw them disap- pearing among the rocky hills, but on account of the roughness of the water and the tossing of our boat they were without effect. About fifteen minutes after leaving the site of the above encounter, we came upon two other large male bears, and had a hard tight with them, in which conflict, however, wl, were more successhil. These little inci- dents, though not exactly coming under the head of surveying, were some of the difficulties we had to overcome, and so I consider it quite proper that they should be mentioned. If an\' of our friends here should have occasion to make surveys in the same district, it would be to their advantage to know what instruments would be found most suited to that particular locality. The traverse of the coast was continued for about seven miles, when the eastern extremity of the outer island was reached, where a line, deep, but narrow channel, was found to separate it from the inner island. The shores were chiefly high, and in som ; places were found perpendicular cliffs of rock standing up from Ave hundred to one thousand feet out of the water. At these places thousands of sea-fowls were see flying about and resting on the ledges along the face of the cliffs, 'l ne birds were not so numerous as to prevent us from getting clear sights from point to point; but just here our progress was again interfered with by the occurrence of local attraction in the shape of a herd of about thirty walrus. We did some clearing here, but nothing very extensive, and then pushed on, p.issinf^ tlie eastern ciul of the islaiul and tlien turn- in;,' sliipwaid aioii^f the south shore. 'IMu; rest ot (jur trip, extemhn^' over about live or six miles, was eoniparatively phiin saihn;,s the only obstacles met with bein;,' one small nerd of walrus and one more polar bear. In some ri'spcets this eighteen or iwent}' miles of coast survey was the most diflicull that I have had to deal with in my expencnee. Just to the south of the Di^'s Islanils a K^'^np "f twenty-fhi' or thirty small islands were also surveyed, antl the main shore tor a distance of about twenty miles south-west of ('ape W olstenholm. Near the south eastern extremity of Nottin},'ham Island a harbour was discovered, and called Port De I?oucherville in honour of the observer left in charf,'e of the station placed there. The positions of the (jasti'rn coast of Mansell island and the southern end of Southampton Islands were corrected in longitude. A portion of Marble Island, in the north-west of the bay, was surveyed, and its geographical position determined. Tl.en, arriv- ing at the west coast of the bay, it was found according to the chart to be half a degree out of position for about one hundred miles south of ('ape lCs(phmo. The true position of tiiis coast having been ascertained, we passed southward and arrived at Fort Churcliill, a place, for various reasons, the most interesting yet spoken of in connection with our voyage. For over two hundred years it has been one of the most important trading posts of the Hudson Bay Company. More than that, it was their chief stronghold against invaders, being protected b} the massive stone fort Prince of Wales until about the 5'ear 1775, when it was taken by the French admiral. La Perouse, and tlestroyed. At the present time it is an important trading station, and possesses the onl) harbour on the west coast of Hudson Bay, and lastly it is destined to be the future: terminus of the Hudson Bay railway, and the Liverpool of Manitoba and the North- west Territories. I have here a chart of this very excellent harbour, prepared from an accurate survey made by Lieut. Gordon and myself. I will briefly describe the methods adopted in performing this work. The first step taken was to erect a number of signals or small beacons at prominent points on both sides of the river and at intervals of about half a mile. Then a level stretch of shore was chosen between two beacons (I and H on chart) and the distance carefully measured; this distance was used as a base line, and from the extremities of it sextant angles were taken to the ottier points (with the exception of one or two, which were fixed by taking angles from other more suitable points, which had been fixed by the other sites). The shore line was then traversed by the compass and fitted in between the points fixed by triangula- tion. Having now obtained a correct plan of the shore line, the next work was to get a plan of the bottom of the river. The diflficulty we met with in performing this part of the work was, not to take the soundings, but to locate them correctly ; for, on account of the ebb and flow of the tides and the currents of the river, it was impossible to keep any kind of a straight line with a boat. In getting over the difficulty our beacons came into use again. At every cast of the lead, 3 8 by the use of two sextants, double angles were taken simultaneously from the centre of the boat to some three beacons on the shore, one beacon always being conmion to the two angles. Thus every sound- ing was an absolute hx, and was plotted upon the chart by means of a station pointer. It was also necessary to note the time when each sounding was taken, in order to be able to make the proper reduction to low water, as at this place the rise and fall of the tide varies from eight to sixteen feet. As may be seen by this plan, the area of water in the harbour within a four-fathom line is approximatel}' half a square mile, and with a very little dredging this area could be consid- erably increased. The mouth of the Nelson River was also surveyed in a somewiiat similar manner, but not so completely, on account of the mucli greater dimensions of the work — the river being fourteen miles wide at the mouth — our limited time, and the less necessity for the survey. Suffi- cient soundings were taken, however, to ascertain the liniits of the channel of deepest water, and to give evidence of the impracticability of making a harbour at York. The Alert was obliged to anchor ten miles outside the mouth of the river altogether, wliere she was exposed to the full sweep of the gales from the north-west, and one night ex- perienced such a heavy sch that it was found necessary to let oil tanks run to prevent the seas from breaking over her. I had intended to give you an account of some track surveys made during the winter season by myself, when travelling about the country on a sled drawn by an Esquimo dog team ; but am afraid that I have already taken up as much time and space as my subject will warrant me in doing. ! i iinultaneousl}' lie shore, one every sound- t by means of ne when each per reduction le varies from area of water nately half a iild be consid- n a somewiiat much greater ss wide at the 5urvey.
