ELECTRIC LIGHT AND COLOUR MANUFACTURE. 



[1853; 



limited, and the supply so uncertain, tbat the article is compara- 

 tively unknown in the Market, and has been consequently contined 

 to a few hands. But by an extension of the operations, from a 

 proper employment of Capital, a vei'y large and constant supjily 

 may be kept up \vith the mercantile community, aud with tbe 

 greatest facility. 



Veins of Specular Iron Ore, and Copper Pyrites, occur in the 

 same Strata as the Barytes; aud the latter may be very properly 

 looked on, if not as a Matrix, still as a very strong indication of 

 the co-existence of other Metalliferous Deposits occupying the 

 same channel of ground. 



This is a feature of considerable importance in a nnning point, 

 of view; as the operations to be directed, in the first instance, to 

 tbe Barytes most necessarily tend to the de\elopment of the Iron 

 and Copper, and may thus be extended, by the same staft' of 

 operatives, to the working of the latter Minerals upon the most 

 cheap aud ett'ective scale. 



Their quality is undeniably rich, butnothing whatever appears 

 to be kuown, at present, of their e.xtent. From the regularity 

 and size, of the Lodes however, already exhibited in the Banks 

 and beds of tlie Rivere; added to the exceeding favourable na- 

 ture of the accompanying strata, little doubt can exist (judging 

 from parallel cases) that they are to be found here in large aud 

 productive quantities. 



Rich specimens of Zinc and Manganese, are to be found like- 

 wise in this immediate locality, evidencing their presence also. 

 But none of these deposits came under my notice, from the natu- 

 ral impediments before mentioned. Such specimens, however, 

 were handed me by the inhabitants who had picked them up in 

 the bed of the river in the summer season. 



Of the various Marble beds or deposits in the Five Islands 

 Distiict, the white most undoubtedly take the pre-eminence; 

 although the variegated, fronj their variety, beauty, and compact- 

 ness, must always stand very high in the scale. 



The White Marble is of the finest quality for purity and grain ; 

 having been pronounced by a roost eminent Statuary, to com- 

 bine all the requisite oharactoristjcs for the most delicate and 

 enduring works of art. Judging fi'om the appearances of the 

 several beds partially opened on ; and their length and breadth, 

 traceable on the surface in the forest, and in tjie bed of the con- 

 tiguous river, there can be no question that this most prized and 

 valuable article, exists (in situ) hei-e, to an extent little suspected 

 by any one, and now, for the fiist time, to be developed to the 

 world. 



the more so, from their immediate contiguity to each other The 

 Layers or beds of the material lie horizontally in tbe face of the 

 bank; and, judging from their compactness and nature, blocks of 

 very large size will no doubt easily be worked out. 



Harbours embracing the most advantageous ]iositions, are 

 everywhere almost in contact with the Mineral Districts, to which 

 access is easy, in most cases, by gentle inclinations; and shipping 

 for the exportation of metals or minerals abundant ; and freight 

 moderate. 



The Province, from the cureovy view I was enabled to take of 

 it, appears to be bountifully supplied by Providence with wood 

 and water, and to comprise, generally, an undulating country 

 of upland and interval; the latter, particularly in the Truro, On- 

 slow, Economy, and Five Islands Districts, abountling in alluvial 

 soils of the richest description. 



From the ungenial season of the year, when nature had put 

 on her most sombre mantle — t'"e vegetable world appeared to the 

 least ad\autage to the visitor. But enough was apparent to sat- 

 isfy me, that, in a few months, a total change will liave ovei'spread 

 the scene — and that few countries can boast of greater luxurianco 

 or beauty. 



The geogi'aphical position of the Province, placed as it is, 

 between two immensely populous and consuming quarters of the 

 globe (Europe and Ameiica) gives it an undeniable advantage 

 o\'er almost every other portion of the civilized woi-ld — and 

 unity of purpose mnonr/st its inhabitants; rapid internal com- 

 munication by ^ai'/roirf* (one of which latter I am happy to 

 find, is now in actual progress, and which will, iu effect, be tbe 

 Luno giving vitality to the whole — and a main artery through 

 which the enterprise, spirit and commercial wealth of those two 

 most important communities mustdirecth' circulate,) and Capital 

 alone, are wanting to render it most wealth}' and prosperous. 



I cannot conclude these hasty notes without expressing my 

 great obligations for the uniform kindness and attention, I r; - 

 ceived at the hands of all clashes of the inhabitants, (from His 

 Excellency the Governor of the Province, to the Native Indian 

 in his primitive Wigwam,) during my very short sojourn amongst 

 them, — bearing out, in the fullest sense, the high chancer for 

 hospitality and kindly feeling, which I had been led to anticipate 

 from them, previously to ray quitting the British Shores. 



I beg to apologize for the length of this communication, which 

 I had intended to have made much more concise, hut tbe very 

 great interest and impoitance of the subject, have led me unwit- 

 tingly on. 



The Variegated Marbles present several very distinct varieties; It will afibrd ine much pleanire to transmit to you, the 



amongst the most prominent are a most delicate Lilac (or published transactions of the "Penzance Natuial History and 



Amethyst) ground, combined with a soft yellow, or gold colour. Antiquarian Society," and to receive from you a copy of your's 



A pure Lilac, with a trifling admixture. in exchange. 



And a Lilac, blended with green, varying in deep and light 

 shades. The former and latter of these represent a Oiallo Antico 

 and Verd Antique, of a true and unmistakeable character — in- 

 volving (from their beauty) the utmost difficulty in deciding to 

 which the palm for merit and value should be awarded. 



Property, of such intrinsic value as these, can no Ioniser ba 

 allowed to remain buried, and unknown in the bowels of the earth ; 

 and the surprise to myself is, how th(»3' can have so long escaped 

 tlie prying eye of man, and wasted their hidden treasures in the 

 desert air. 



Nature h:is so arranged and placed these beds in the rivor 

 bank, (here a"=suming a height of several hundred feet) as to render 

 their being quarried with the utmost ease and cheapness. And 



I am. Sir, 



Your most obedient Servant,
