telegraph, which, however~ the Company proposes to lay down along the whole of this branch, and which will be slill more satisfb,etory, because if any accident should occur to prevent one train from reach-. ing the central or junction station in proper time, the circumstance may be made known at that station, to do away wit}, all suspense and, if' such accident should entirely stop, instead of' merely delaying, the train, it may be got into a siding, of" which there will, no doubt, be several, and when this is made known by telegraph, the trains mo~/iug in the opposiu; direction may proceed without being stopped also. After havi~g fi~i.slmd my i~speetion of the proposed branch from Blisworth to Pcterhorough, 1 retu,'ned by" way of t-[ut,tingdou, Camh,'idge, Chesterford, Newport, Bishop Stortibrd, in order to view the ground over whi(:h it is proposed that the extension of the Northern t~r~d Eastern Railway shall eventually pass : and o[,e thing is eertah b lhat, i[' this exiension should ev~'r take place, no passengers fl'om Pe{erhorough, or lhe vicinity of l,ondon, will go by the circuitous route ~[" Blisworth ; so tlmt the brat~ch which fbrms the subject o[' this letter, will be confined to t,~ ? traffic of the valley of" the Nen% along which it is to pass.

Preservi~g Ygmbe,'. Payne's Patent for preserving tirnber from tile ravages oJ7 the dry rot, insects, &e., is now likely to be brought into extensive operation; the process consists of impregzmti,~g timber with a solution o~(' the sulphate of' iron, and forms an insoluble chemical preservative, and by the process adopted, impregnates the timber to the very centre; this is efl'eeted by placing tile timber i~l large fret, tanks with the solutions, and then first exhausting the air, and afterwards readmilting it, and then using a fbree-pump, with a pressure of" 200 ibs. on the square inch, to force tile solution into the heart of the wood, which it does very effectively. Don, as a preservative to timbe b has long been known, and it is now~ through the ingenious process adopted by Mr. Payne, likely to become very extensively adopted. The Company is now preparing the timber to be used at Claremont, for the royal stables, by command of the government. Cir. Eng. and Arch. aour,
