Mr. French, to whom this province is under great obligations, had proved that com- paratively little was known oi' the extent of the productive measures, and that similar discoveries mnst soon be made in other directions. The explorations, whieh are the subject of this paper, were personally superintended by myself, and ^vere cojiducted by the aid of a mining engineer on the following properties: — Xo. I., situated on the south western side of the coal basin, on an area known as " the Culton properly,'' and adjoining the colliejy of the Intercolonial Company: No. 2, on the south eastern extremity of the l)asin, on tlie \si'st llaidi of McLennan's Alountain. Xo. ;), iit the eastern end of the basin near the waters of Alerigomish, on a properly called the St. Lawrence area. No. 4, on a pro})erty on the northern side of the basin purchased from Messrs. McDonald, AlciCay and Known, on the East River colliery. No. 5, on an adjoin- ing i)roperty, jiurchased from Messrs. Beal and How, and now belonging to the Montreal and Pictou Coal Company. These explorations, therefore, arc the most extensive that have hitherto been conducted in that county, and though imdertakeu for the practical purpose of discovering and developing coal mines, have incidentally thrown some light on the Pictou coal fields, which may be interesting to geologists and to the public. I shall first select those explorations on the northern side of the basin, on the East River and Montreal and Pictou properties, as they are in the immediate vicinity of New Glasgow and in a district which had been previously fully described and some- what misunderstood. I O-i l)i'. Dawson, wliu,st! iiivostii^iitioiis have tliiown so inuoli li- hnc' been allected by subsequent denudation, lint so far we have no equivalents of the southern coal measures in the northern basin, and nmst assuine that they were always distinct basins, and now ditler, from their measures having- l)cen formed under different circumstances, [n October ISfio operations were conuneiu;ed on the East River colliery, which was purcliased for the jjurpose of working some upper seams of excellent (]uality which had already been tested. Finding while I Avas proving a small seam Icnown as «' the Richardson seam," near New Glasgow, that it dijiped almost the reverse Avay to those of the Albion Mines, and that its underlying strata rested on the conglomerate, and that the conglomerate itself neai* New Glasgow dipped to the southward, and various dips on the west side of East River having indicatcl that the coal measures must come to the sni'face or crop near New Glasgow, I prepared the plan now exhibited, showing the supposed course of the northern ero]) of the main seain at the town of New Glasgow, and also on the west side of the river. Wc felt so assui-ed of the fa<,'t that the Albion seams, instead of being half a mile deep at Xcw Glasgow, must come to tlie surface, that we purchased the bed of the river and the property to the westward, and commenccid explorations on the sn})posed line of crop. The first trial ])it on the edge of the river was successful, as it struck the cro]) of tlie main seam, which was foimd lying at a heavy angle. Following the course indicated by the plan, we sunk a trial {)it nearly half a mile to thc^ south- westward, where "\ve again struck the same outcrop. A working shaft was then sunk, and the results arc thus described in the official repoit of the go\ernmcnt Inspector of Mines : — " A company has been formed with the title of the Mo.^a'cal and rictou Company, to work the seam which has recently been opened by II. G. Malil>urton, Esq.. on the west side of lOast river, and adjoining the Ali)ioii mines on the north. A shaft has been sunk through .-several beds vi' coal, varying in thick- lics,*^ iVom if'j;' lo !.»'.<; '. ;iii(l sci)ai';it('(l l)V IkmIs ol" lire cJay (Voin 7 to 10 {'itct thick. I'liov (lip to the soiiih-cast at an aii, which coiisislcd of shiik'?.. The >.iii'l;ico drift, Avhich was very dcei), eoiitaiiied pai-ticles of eojil. The search Avas unsuccessful, as the explorations were evidently in the centre of the basin. The Albion mines shales are a distinguishing feature of the liasin. Their enormous thickness is Avithont a parallel, and as I hey overlie the large seams, they arc a sure indication that the crops of the seams must be sought * to the rise.' These shales serve to identify the ('ami)bell or Culton seams with ' the main seam' of the Albion mines. To the south-west of the Culton l)it the measures were found to assume a north-Avesterly dip, while near Oliver's mill, a mile farther Avest, the measures Avcre found to dip in the reverse Avay, shoAving that the coal basin must SAveep off m that direction and l)etwcen the two points in question. More; than a uiile to the south of the Campbell area coal and tire-clays have been found by us, Avhile the existence of the light sandstones of tluf Pictou coal fields still farther south, established the fact that the coal basin must turn in that direc- tion. For two seasons this property has been explored by us, and as Ave are the only persons by whom it has been examined, the results of our explorations Avill have more Aveight than theo- ries, hoAvever ini^cnious, bv others Avho have never examined the locality. The extension of the coal field in this direction is most important, not only from the very superior (quality of the coal, but also because it is found at so short a distance from the provincial raihvay. A leA-el Avas driven by us a short distance on this seam, Avhich Avas found to lie at an easy angle, the mea- sures on this area being Hatter than in any other part of the Pictou basin, excepting Avhere the upper seams occur, Avhich generally lie at a slight angle, and are consequently as to their angle of dip and their out-cro[), unc()nformal)l<' Avith the larger and lower seams. The seam, Avhen folloAved in from the out- crop, increased, in a fcAv yards distance, from two feet to between three and four feet, and a bore hole a few^ feet farther to the di}) went through six feet of coal. ShoAving that at a moderate depth we may expect to find it assume its full size. It AA^as overlaid by oil shales similar to those over the main seam near INIiddle and East rivers, and in the overlying shales Avere found fossils similar to those above the main scan near Middle river. SMi \x St. Lawuknci': Area. — On tliis area which is near Mori*;-oiui.sJi harbour, and is the casteni t.'xti'cnuty of the basin, oxi)lorations were carried on from Fe))rnarv lyGO until February 18(17, under tile charge of a mining engineer and of a veiy competent oreman. The outcro}) of the seam had been tirst struck by- others ; a pit Avas sunk (;ne hundred feet deep, and kneels driven from it. There ap[)eared to be what miners call a ' saddle-back' where we stiuk. The dip was over G0°, l)ut flattened greatly at a few hundred feet distance to the dip, and varied from S. W. to S. E. To the eastward the measures dip in a sonth-easterlv direction, and lie at a very '"isy angle. The seam Hrst found proved at a depth of one hundred feet to ))e fourteen feet from roof to floor, though near Uie (Uitcrop it had not been as many mclics thick. It was intended to have ouened a collierv at this pit, as it is some miles nearer deep water than any other, but the disturbance at the spot selected will render it necessary to sink a new working shaft. The one now sunk will answer for a ventilating shaft. Numerous pits and bore holes have been suuk on the property in order to prepare for opening a colliery. A few feet from the last naiucd seam another was found eight feet thick of ver}^ good coal. It has not been tested to the dip, and pro])ably will prove to l)e an underlying bejich of the other seam. The explorations on the McBean area adjacent, show that the seams found on it must be found also on the St. Lawrence area, which is probably on the northern side of the basin. A large amount of shales was foimd to overlie the scam proved l)y us. A few yards from the pit we found a reddish sandstone which occurs in great abimdance along Sutherland's r iver, and dips generally at a very slight angle. It is proljable that reddish sandstones on the Culton area are identical Avith those found en this area. The occurrence of sandstones in difl'erent localities cannot be counted upon, as the Albion mines, in sinking their Dalhousie pit passed through nothing ])ut an immense mass of shales, Avhilc further west to their surprise they came down upon a light sandstone in sinking a shaft, and for a time at least abandoned it, supposing that the coal must have run out, and that the sandstone l)elonged to measures underlying the main 8 scam. The same saiid.stoiic has been luuiid in the oveilyuig shales at New Glasgow and at Middle ri^er. I am disposed to think that the lower measures at Sutherland's river bridge are the equivalent of the New Glasgow conglome- rate, and like it, are the boundary between the southern and northern basins, or as I have termed them, the Albion and the Pictou basins. The southern basin narrows and terminates a short distance to tlie eastward of Sutherland's river. I have found coal at its eastern extremity, and also have seen caunel coal discovered there. The explorations east of the river were merely superlieial, being confined to examining exposures of strata*^ and indications of coal. I speak therefore with some hesitation as to the country east of Sutherland's river. That there is coal there, may be safely assumed ; but the extent of it must be settled by the miiier's pick, and bore rod. No intuition can dispense with the drudgery and expense of practical explo- rations, which require a very .mall amount of science, and a very liberal expenditure of money. The accompanying map of the Pictou coal district gives the boundaries of leases, &c., accordhig to maps of the Mines Office. \^ ■A-
