THE CIVIL ENGINEER AND ARCHITECT'S JOURNAL. 



[March, 



moveil the stupen.lous paddle-wheel and again attached it in an incredible 

 Thoi t spuce was exhil)ited, it surprised the naval officers, who had never 

 witnessed anv thin^' of tlic liind before. 



Romil Mail Steam Packet Comp,w,,.—Tbe Medrvaij, another of this com- 

 nanv's vessels, built bv Mr. I'itcher, with engines of 400 horse-pmver. Ijy 

 Messrs. Maudslay, Sons, and Field, made an experimental trip down ihe 

 Thames at the beyinnin- of last month. She performed the trip to the 

 admiration of all on board. The interior fittings combine l<cth taste and 

 convenience, and are in perfect accordance with the magmlicence of the sliip 

 and engines. Another ve^sel. the Trent, with engines by Messrs_ Miller and 

 Eavenhill, was to le.ive the Thames for Southampton on the iithult. :He 

 shall notice this vessel next month. 



Plmnouth Feb. 14.— Tlie siiles of steam vessels on which coal boxes are 

 fitted are ordered to be lined with sheet copper. This is in some measure to 

 prevent the shin from taking fire, should (as on board the Avon) spont.nncoiis 

 ignition of the coals occur. Means for lietter insuring the safety of the creu- 

 and passengers, in the event of lire obliging tliem suddenly to abandon the 

 vessel, are also now provi.led by the Board of Admiralty, at the recommenda- 

 tion of the committee of master sbipw rights, ordering boats o two thick- 

 nesses of phnk. lined between with felt, to be fitted to the padd.e bo.xes of 

 steam vessels. 



Steam Navii.—li is in contemplation to increase the po«er of most of the 

 steam frigates now in the service, the whole of which, with but one e-'^cP" 

 tiun, are considered not to have sufficiently powerful engines for all the 

 curposes for which a steamer may be required ; that although their present 

 power may answer very well in fair weather and smooth water, yet at the 

 time their services are most required, in a squall on a lee shore, it wilf 

 scarcely enable them to hold their own, much less to assist other ships, liie 

 Devastalion, fi^reu. Gei,ser. Driver, and Styx, are ste.im frigates of about 1,100 

 tons each. The Devastation is the only one of them that has suthcient power 

 —her engines being 400 horse jower; the engines of the others being only 

 285 horse poiver. 



MISCELLANEA. 



Railways Report.— The Officers of the Railway Department have pre- 

 sented a Report to the Earl of Ripon. President of the Board ot Trade. 

 This report, which is presented to Parliament by command of Her 

 Majesty, is dated the 5th of February, 1842, and contains a voluminous mass 

 of interesting information relative to railways. From the returns ol accidents 

 it .appears amongst other things, that during the year 1841 the number of 

 accidents on various railnays, which arose from causes beyond the control 

 of passengers, or, in other words, from carelessness, and want of proper pre- 

 cautions on the part of the r.ailway companies or their servants, amounted to 

 29. By these accidents 24 persons were killed, and 72 injured. During the 

 sameyear there were 36 accidents attended with personal injurv to individuals, 

 owing to their own negligence or misconduct, by wdiich 17 pers ms were 

 killed, and 20 injured; GO accidents occurred which were attended with per- 

 sonal injury to servants of the company, under circumstances not involving 

 danger to the public ; by these accidents' 28 individuals were killed, and 36 

 injured. Thus there were altogether 62 human beings wdiose lives were 

 sacrificed by accidents on railways during the year 1841. 



River Bourn, or Intermitting Springs of tlie Nortli Downs,— In the Journal 

 for March 1840. vol. iii., page 103, we gave some particulars of the outburst 

 of this remarkable spring in the vallev near the Half Moon Inn at C^atterbam 

 Bottom, on the turnpike road from'London to Lewis. We therein stated 

 that the outburst at that time was remarkable for its having taken place 

 at a much shorter interval of four years ; however, in November last, being 

 an interval of not quite two years, the spring burst again, and has continued 

 llowing. without intermission, to the present time, and has given forth a 

 much larger volume of water. We refer our readers to our lormer article for 

 the particulars of this interesting phenomenon, and invite the attention of 

 the scientific and the engineer to the subjects. To the latter it is important, 

 as the occurrence of these springs are not unusual in the chalk formation, 

 and at the last outbreak of the one in question, the engineers then construct- 

 ing the works of the Brighton Railway suffered a serious inconvenience in 

 consequence of it. It is most likely that the inlerv.al of the outbreaks depend 

 upon the quantity of rain that may have fallen, as last year was remarkable 

 for being very wet.

TO CORRESPONOENTS. 



We hare received a letter from ilfosri. Brnithwaite . Milner, and Co., in whicli 

 then state that the appuralui for diseomiecting the paddle-wheels oj steam vessels 

 is the invention and patent of Mr. Trewhilt. Tliey have also favoured us by a 

 corrected drawing, showing 'the eonnertiou of the apparatus with the crank and 

 the engine, wliieh we shair insert ne.rt month, together with a commmucation on 

 the same subject from Mr. Grantliam. 



The swgested improvement of Amicus Machinarum, on Messrs. Maudslays and 

 Field's winnlar ci/tindcr engine, by placing the air-pump in the central space will 

 not do- tlie ren/'oliject for wliich the annular cylinder was contywed, being Jot 

 the purpose of getting a long connecting rod, is entirely lost m A. M. s arrange- 

 ment. 



A. will be noticed ne.rt month. 



The communications on pile-driving are again deferred, as we have not as yet 

 come to am/ satisfactory conclusion as to the actual force of tlw ram. 



B. R. iVe do not consider the apparatus for preventing accidents on railways 

 would answer the purpose supposed by its inventor. 



jfrricoli.-We -will endeavour, in .•:ome future number of the Journal, to give a 

 fable showing the variation of the .Magnetic Needle yearly. 



The Gorgon Engines.— Jl'e have received two communications in ajiswer to 

 " Vulcan,'' which we regret, on account of their importance, we are obliged 

 to postpone until next month . 



Boohs for Review must be sent earlif in the month, communications on or before 

 the 20th (if with drawings, earlier), and advertisements on or before the Zat It
