potato, and thus saved it from disease. He, in fact, acted on the 

 principle of counteraction by means of the issue^ using a pea

T/ie Potato Disease, and Cutting off the Haulm. — i lately 

 paid a visit to Mr. Diploc-k, of the Gritiininu, Fk-tchiug, vihich. I 

 have done for three yeare in succession ; and as Mj-. D. has been 

 ver3" succes-sful with his potatoes, not having one diseased tuber 

 for the hist three yeai-s, while his neighboui-s around hun have 

 liad to deplore nearly the entu-e loss of theii-s, I give you the 

 mode whereby he prevents the ravages of the malady. As soon 

 as the slightest symjitoms of .dise;ise are manifested in the leaf, 

 and before it has reached the stem, Mr. D. has the tops cut off 

 close to the soil, at the same time in passing he presses in with 

 his foot the to}) left behuid ; they are then thickly earthed over 

 to prevent bleeding ; and if the soil is observed to be damp a few 

 days after, a fresh coat of soil is added. It is to the pi-eventing 

 of the bleediusr that Mr. D. attributes his success, as he finds by 

 this mode that" the potatoes swell and grow as usual, while those 

 left uncovered become exhausted by bleeding, and grow no larger. 

 Mr. Diplock has now a fiue healthy crop of potatoes, and not a 

 diseased tuber among them, while every other grower in this 

 ueifi-hbourhood finds theii-s more or less diseased. — Wm. Wood,

The affects of Liquid Manure. — An extensive landed pro- 

 prietor, in Ayrshire, writes us (the Glasgow Daily Mail) : — 

 " You say that twenty sheep can be kept on an acre of Itahan 

 rye-o'rass. I know that many more than that number can be 

 kejJt on a Scotch acre of it. At present there are about seventy 

 sheep, of about twenty pounds a quarter, fed on a Scotch acre of 

 Itahan rve-"'rass per month. \Yhen fii-st put up in the peus, 

 within doors, each sheep eats twelve pounds per day of Italian 

 rye-grass and half a pound of rape-cake ; but as they take on 

 fat they o-raduaUy fall ofl' eating as much per day of the Italian 

 rye-o-rass, and can consume not more than eight pounds per day. 

 It is quite wondert'iil what a quantity of Italian rye-grass, watered 

 with the liquid manure, can be cut from a Scotch acre. It can 

 be cut four times in the year, and the weight of the four cuts is 

 upwards of forty tons of moist Italian rye-grass." 



CORRESPONDENCE. 



Correspondence relative to the estahlishment of communication 

 between the Society of Arts, Manufactures and Commerce 

 (of London,) and the Canadian Institute, with a view to 

 advancing the knowledge of the resources and capabilities 

 of Canada abroad, and of promoting information on the 

 same subject within this Province. 



Copy of a Letter from the Secretary of the Colonial Committee of the Society of Arts, 

 to the Corresponding Secretary of the Canadian Institute: 



Sir, — I am instructed by the Colonial Committee of the 

 Society of Arts, to acknowledge the receipt of your letter of the 

 31st July, (see August No. of Canadian Journal,) and the 

 various papei-s which accompanied it, transmitted to the Right 

 Hon. Sir J. Pakington. The Committee are much gratified by 

 the cordial promise of co-operation with which their proposal 

 has been met by the Council of the Canadian Institute and trust 

 that the correspondence thus commenced will hereafter lead to 

 important practical results. 



The Committee consider in the fii-st instance that it would 

 greatly facilitiitc future enquiries if you would be so good as to 

 have a general list of natural productions and raw jiroduce of 

 Canada pro]iared and sent to me. This list should include as 

 far as possible, the name of every substance, whether mineral, 

 vegetabli', or animal, occurring or being produced in the colony. 



whether used or known in commerce, or not, indeed it is m fact 

 even more important that the list shoidd include the Latter than 

 the former, as the chief object which the Connmittee have in 

 view is, to become acquainted with those productions which are 

 not yet known in commerce. It would be of advantage if in 

 the enumeration of these substances the local or native names were 

 given, in addition to the English or European ones, accompanied 

 by memoranda of any uses to which the substances are appli ed 

 and of the probable facility with which they could be supplied in 

 large quantities should a demand arise. If there are, however, 

 any productions, not at prft5ent articles of commerce, the value of 

 which you are desirous of having ascertained, I am desired to invite 

 you at once to send them over to the Society, and they shall 

 immeliately be brought under the notice of competent persons 

 for practical examination and report ; as in so doing it is for more 

 satisfactory to make trial of any new substance on a manufactur- 

 ing scale, it will greatly facilitate the laboui-s of the Committee if 

 you will send large samples, say of at least a half a hundred 

 weight of any gum, resin, oil, dye-stufls, fibre, ornamental wood, 

 and at least ten jjounds of any metalUc ore or stone. 

 I am, .Sir, 

 Your's verv faithfully,

Geological Survey of Canada. Report of Progress for the years 1850-51. 

 John Lovell ; Quebec. 

 Another of Sir. Logau's admirable Reports of Progress made in the 

 Geological Survey of Canada has reached us. Mr. Logau's absence 

 from the Provinces during the year 1850-51 for the pui'j^ose of super- 

 intending the anangement of the collection of economic materials 

 forwarded from Canada to the Exhibition of the Industry of all Nations 

 in London, prevented him from reporting at the usu.al time ; and owing 

 to the expiration of tlie Provincial Act of 1345, making provision for 

 the survey, and the unavoidable lapse of time before it could be 

 renewed, the season available for field exploration was considerably 

 curtailed. Notwithstanding the drawback last mentioned, the Report 

 contains some highly interesting information, and shows that consider- 

 able progress has been made in some of the important details of the 

 survey. The subject of the distribution of gold possesses much attrac- 

 tion at the present period, and in its relation to Canada has received due 

 attention from Mr. Logan. 'We append that part of his Report which 

 relates to this important subject : — 



" In tlie Report of Progress preceding this, mention is made of a 

 partial examination of the gold-beaiing drift of the Chaudiere. This 

 examination was last season continued, and the facts resulting from it 

 constitute the only additional topic to wliich I have to invite your 

 Excellency's attention. The am'iferous district was found to spread over 

 an area probably comprising between 3000 and 4000 square miles. It 

 appeal's to occupy nearly the whole of that part of the Province which 

 lies on the south-east side of the prolongation of the Green Mountains 

 into Canada, and extends to the boundaiy between the colony and the 

 United States. Two general lines of exploration were followed : one 

 of them up Uie Chaudiere and Ririere du Loup, from the seigniory of 

 St. Marl' to the Proriucc Line ; and the other from Lake Etcherain to 

 Sherbrooke, on tlie St. Francis. The former, running transverse to tlie 

 rock r.anges, measmcd about forty-five miles ; and the latter, with 

 them, about nhiety mUes. The ti-ausverse line was more closely 

 examined than the other, and traces of the precious metal were met 

 with at moderate intervals thioughout the whole distance. They were 

 not confined to the channels of the main streams merely, but tliose of 

 various tiibutiuies furnished indications sometimes for a considei'able 

 distance up. 



"Tlie lowest point in the valley of the Chaudiere at which the drift 

 yielded tr<-iccs of gold was ou a small stream, falling iu on the left side 

 of the river, not far within the siuith-eastem boundary of the seigniory 

 of St. Mary. They were found to occm' on four tributaries in the 

 seigniory of St. Joseph, for distances of one and two miles from their 

 mouth.s. One of lhe.se joins the main stream on the left bauk. about a
