inch thick, are stnoothlj* cut by a diamond, and then it is ready for market in a statu known 

 ' roiijjii plato glaaa.' The whole process of ciistinjj is not only interestini^ but exciting. The men 

 are drilled to move promptly and silently, hrindling tlicir ini|iK'mcnt8 with great adroitness. The

"The comj.nny do not as yet polish their glass to fit it for windows or mirrors, but are about 

 to introduce the machinery necessary for that purpose. At present there is sufficient demand for 

 the rough plate, to be used in floors, roofs, decks, Ac, to keep their Works constantly employed. 

 They can produce plates two inches in thickness, and one hundred and twenty by two hundred 

 and forty inches square, a new table weighing thirty-two tons being in readiness for castings of 

 the latter dimensions. It is believed that plate glass of great thickness, at a low price, will be 

 introduced for many purposes for which iron and stone have hitherto been used. 



" The duty on imported glass is thirty per cent.; but so bulky and fragile is the article that the 

 duty, expenses, and breakage, amount to near ninety per cent. Tiie fact that the company own 

 a water front, and can ship directly from their works, is an important consideration in avoiding 

 loss from breakage, affording at the same time advantages for receiving fuel, sand, and other 

 material, direct 



"The construction of the works commenced on the 1st of February, and the first casting was 

 made about the Ist of May, giving proof of a well digested plan and vigorous execution. The 

 works are at present capable of producing seven hundred feet of three-eighths inch glass per day. 

 The furnace holds twelve pot'', and there are twelve annealing kilns, each forty by eighteen feet 

 The fires, kept up by Cumberland coal, are not allowed to go down until the furnaces are 

 destroyed, which generally occurs after a year's use. The pots after a casting are at once 

 returned to the furnace and re-filled ; they usually last a month. The temperature of the estab- 

 lishment is decidedly high, above the top of oidinary thermometers. The furnace fires are 

 watched, as i? a solar eclipse, through dark colored glass, the intensity of the light being nner.- 

 durable to the naked eye. The appearance of the 'sea of glass' when poured over the table is 

 extremely beautiful. At first of bright whiteness dazzling to the eye, it rapidly changes to pink, 

 scarlet, crimson, and a dark murky red, streaked with black, in which state it is thrust into the 

 kiln. 



"It would be unjust in alluding to previous attempts to manufiicture plate glass, not to men- 

 tion the Cheshire Company, whose success was comparative, but whose failure was positive. 

 Under grave difiiculties they did produce some plate glas«, but ultimately abandoned the scheme, 

 submitting to a loss of nearly two hundred thousand dollars." 



Parks in the Cities of New York — The Great Central Tark. — T\'hen the time shall come that 

 enterprising men on the Desert shall enclose one of the Oases for a pleasure ground, there will 

 be a propriety in designating it as — Mungo Park. Before adventure and enterprise shall have 

 gone thus far, the labors of our Commissioners will have been completed, and this city will pos- 

 sess a Park, one that will realize all that its friends have uttered in fivor of the project, and one 

 at which howsoever heartily this generation may scold, the New York of the next century will 

 prize beyond any other remembrance of our day. The eminent and honorable gentlemen who 

 are now engaged in the labor of averaging the titles and conveyances necessary for adjustment, 

 before the people shall possess their own, are of those whose highest object it is to do that import- 

 ant work so well that their names shall be identified with its complete success. Gov. Bradish, 

 to whom all the pleasure grounds of European cities are familiar, means that this emerald, in 

 rock-setting, shall be worthy of admiration even from those to whom the great Parks of London 

 and Vienna are familiar.
