GURN'RV'S STF.AM COACH. 24!^ 



Most persons living- in the interior of the country, know that the 

 bark of the swamp-maple will make good black ink. thouiih they 

 mav not be aware that ifoiir nonn.ls of this bark, dried and <,o(V)>d, 

 are equal to one noiind of the bes) <j,alls. The black obtained fi-om 

 this bark is equally as permanent as that from galls, and as the 

 bark gives a much smaller portion of extraneous precipitate, it will 

 clean better, and make a much !)righler color. Those dyers who 

 formerly used nutiralls, will know what quantity of swamp-maple 

 to use to a given quantity of logwood ; but I should suggest to 

 more modern dvers to leave out one pound of logwood for every 

 poMud of bark used by them. 



Some (cw of our wor-llen dyers have, at mv suggestion, used the 

 maple bark for three or four years, and their colors are much 

 esteemed both b^'^ dealers and consumers. Should the colors 

 prove too blue, they may be altered to any hue by the use of su- 

 mach or alder bark. VV. P.

GTJRNEY'S STEAM COACH. 



This beautiful specimen of mechanical invention appears at 

 len<j;th to be brous^ht to a state of perfection, beyond which we 

 hardly think it possible to make any essential improvement. We 

 had an opportunity of witnessing the operation of this machine on 

 Wednesday last, through the Albanv road, and the streets adjacent 

 to the R()gent's Park ; and we should say its progress could not 

 have been less than at the rate of 12 miles per hour ; and in some 

 parts of the road, where the rain had not rendered the gravel ex- 

 tremely heavy, the speed of the carriage could not have been less 

 than 14 miles an hour. From the late improvements by Mr. Gur- 

 ney, with a view of producing a uniform supply of water to the 

 boiler, (or rather the steam generating pipes.) and also in order to 

 produce a regular blozoer. or current of air, through the tire-cham- 

 ber, the difficulties which maintain an adequate supply of steam, 

 appear to be completely obviated. To persons not acquainted 

 with the numerous difficulties which present themselves in bring- 

 ing into full operation such a complicated piece of machinery, it 

 would be difficult to obtain an adequate opinion of the merits of 

 this invention. We have, from time to time, examined its pro- 

 gress in detail ; and we have no hesitation in saying, that the ar- 

 rangement by which the supply of water to the steam-pipes is 

 ejected by Mr. Gurney, is one of the most beautiful specimens of 

 ingenuity we have ever witnessed, amo ig all the curious applica- 

 tions of the steam engine, either for stationary purposes or for pro- 

 pelling vessels, 'i'he difficulties are almost inseparable, in order 

 to reconcile the necessary power required for propelling a carriage 

 of this kind, with the prejudices of fashion which prevail, with re- 

 gard to the appearance of a stage coach. The necessity of con- 

 sulting appearances, has, in fact, greatly added to the difficulties of 

 bringing this invention to perfection, as a vehicle for passengers.
