ADVANTAGES OF GAS LIGHTS. QQ^ 



a great heat, and lasts much longer. 1 may say two fires of Co k burns 

 coak will last longer than three made of coal, so that I do tTian^Coaf^' 

 think that coak, bought at its present price, is equally as 

 cheap, if not cheaper, than coal. Therefore manufactories It would put 



would experience no difficulty from the increase of coak, as ^^°^, ^° '^^^^ 



'■ •' works and 



each manufacturer would burn his own coak: it would be hence an ad- 

 only the coak produced from lighting the streets, that would ^^''onal supply 

 be required to be sent to market, and that only in the win- 

 ter quarter; and if no coak was made at the coak works, 

 and in fact, the demand on those works would in a great 

 measure be at an end, they would be forced to bring their 

 coals to market. 



I do not think then the coak made would be so much above The coak 



the demand, for it is only in large manufacturing towns, where ^°"^^ "ot 



•'. . *^ , . , -n / much exceed 



coaks ai'e used m quantities; and in those towns, it they use ihe demand, 



the gas, they will make perhaps as much coak as they may 

 want on the spot; they will therefore save all the expense of 

 the carriage of the coak from the works where it is made. 

 Besides, were they to sell it, they could afford it much 

 lower on that account ; for, when the coak is made at the 

 works, the gas is all lost, beside the expense attending the 

 making, and the carriage of it to market. It might there- 

 fore, if the streets were to be lighted by it, be afforded at a 

 lower price, if it was found that more was made than could 

 be used in the regular way, to people who would burn it in 

 their stoves. It would certainly make a reduction in the pro- and therefore 

 fits calculated to arise by lighting the streets, if it was sold 'he price 

 at a lower price ; but this I do not think would be the case, jjj^';^^ lowered, 

 as the demand, especially in times of good trade, is always 

 great.

sixpence to twenty shillings per gallon since the stoppage of

would always be a source of considerable profit, and make
