The Select Coramittco appointed hy the Legislative A.laced on the joint did this weight produce the sliglitest movement or visible impression. This would be eciual to 72 tous upon tbo six wheels. struct a line cheaper than upon any other plan ; and if all the advantages presented by the wooden system are not worked upon, and the object sought, cheap and substantial railway com • munication, is .- t kept prominently in view, why the less that is said about wooden railways the better, and the whole report of the Committee becomes a misconception, as it is based only on the cost of the permanent way, whereas the consideration of total cost, and not the cost of a part, appears to me the chief object referred to in the instructions to the Committee. The two engineers to whom I have before referred, give their preference to the plain rail, as being simpler and cheaper. Undoubtedly it is both, nor will any one dispute that a straight piece of wood is about as economical as regards first cost and as simple a way ot making a rail as is likely to be dis- covered. But between this and complication there is a wide diiference, and as well might the fish pieces of an iron rail be declared complicated, and the whole system have been rejected because it adds about 3,600 additional pieces to every mile, of which about 2,400 are bolts, and whicli do very frequently get loose from vibration. The whole of my system is of wood and free from that objection, and from the simple way in which the parts are brought and held together, there is not one piece so likely to get loose as the ends of the plain rail, and which liability, from Mr. Hulbert's own evi- dence, it appears he is seeking to rectify. Mr. Legge, engineer-in-chief to the proposed Northern Colonisation Railway, visited the Clifton and Lanorae lines for the purpose of forming his opinion on the two systems, and after having inspected them in operation, reported in exactly the same sense on the weak points of the plain rail, as woi thu (I syst of mg ■ as the remedy suggested by Mr. Ilulbert in his evidence, would shew he was perfectly aware of. Mr. Legge reports' thus upon Mr. Hulbert's plan : " Two serious objections, in my opinion, exist to the Clifton system of wooden track, and arc as follow : " 1st. The rails arc laid longitudinally, exposing the fibre of the timber, in the weakest condition to the traction, caus- ing it to crush or ' broom up.' " 2nd. The joints in the rails occurring at short intervals of 12 to 14 feet, without assistance of the chairs or fish plates of the ordinary iron rail, cause an uneven surface to the road. The engines and rolling stock, in passing over the line, at each inequality, impinge on the rails to a greater extent than if they were uniform and continuous, and thus increase the destroying agencies ; while, at the same time acting prejudicially on the rolling stock itself. " These two leading objections have been surmounted in the < Foster system.' " * To remedy these damaging points Mr. Ilulbert suggests a compound rail to prevent " the wearing at the ends" and to keep " the rails more smooth." It appears, therefore, that, in the opinion of both these practical men, who spoke from observation, the plain rail is not what is rc.iuired to constitute a good wooden road. Mr. Moberly suggested "^i wooden fish plate notched and bolted at each joint," and Mr. Tully proposed " fish plates at the joints, and instead of fasten- ing them with bolts to fasten them with wedges. " The mode •Mr. Legge was not called before the Committee, but of the thre gentlemen who were, or who gave evidence, I believe not one of them had ever seen either of the plans in operation. 8 of carrying out this idea I tlo not exactly understand, although Mr. llulbert replied that the plan had been tried but " found impracticable." I am very much of opinion that any thing like afishpiecc would be perfectly useless in wood. Mr. Mok'sworth approved Mr. llulbcrt's plain rail in all its sim- plicity. INIr. Tully considered the " compound rail of j\Ir. llulbert the cheapest and best." At any rate, according to all the foregoing opinions save one, something better than a simple straiglit rail with butt joints fastened with wedges at the enils has to be provided. For reasons which I have before given and which are now further confirmed by additional experiments on adhesion, I believe that the rail with the wood endways will prove the " cheapest and best," nor can the simple way in which each block is secured in its seat upon the notched longitudinals be in any way tortured into a complicated machine ; I have con- setptcntly never referred to other modes of making wooden rails, which I bad first schemed in order to avoid the evils of the plain rail system, either of which may be called compound rails, but which I call "vertical-joint rails." The sketch, fig. 2, shews one of these rails. It is simply the plain rail 4 inches by 7 inches, cat down the middle. This rail is held together witn wooden pins at every two feet, and keys in the sleepers ; between the two pieces of rail I insert a thickness of paper dijipcd in tar or marine glue ; the two rails overlap each other one-half their whole length. In put- ting tlie rails togc'^er I reverse the direction of the fibre by turning one of the pieces end for end, and thus get a mor^ ecjual adhesion for the wheel which ever way the engine may be travelling ; but what is of far greater impor- Th 5 shri T 9 tancl, although )een tried but nion that any in wood. Mr. in all its sim- id rail of jNIr. !, according to better than a 'ith wedges at ivhich are now an adhesion, I will prove the in which each )ngitudinals be e ; I have con- laking wooden lid the evils of [led compound 1 sketch, fig. 2, 1 rail 4 inches held together 1 the sleepers ; thickness of ;he two rails igth. In put- oction of the end, and thus L ever way the greater impor- taice, I provide against the want of uniformity in strength and soundness which exists in every piece of wood 12 orll I-Uj. 2. feet long, for by this method two weak points arc hardly ever hkely to come together, and close observation of the plain horizontal system shews that every one of these rails bc'^in to " broom up" at some weak point, which weak point would be enormously strengthened by a.lopting the plan proposed. The way of putting them together so as to secure a close jomt ni the middle may also be well to explain here, altiiouc^h of course the practical man will recpdre no such information. My oi)ject is, however, to make the different systems clear to all who may take any interest in the matter. All timber shrinks (after it is cut into planks) away from the centre of the tree, that is the convex side of the plank is ahvavs next the II 10 heart, thus " a " is a tree we are about to cut into planks, as shewn by the dotted lines ; " h " represents the form each of these planks will take if left to dry thoroughly before used, the planks on either side of the centre turning their convex side to the centre, and the centre piece becoming taper at each edge. The timber used in a railway would hardly ever be dry, but the pieces forming the rail would be put together, so that when they do try to change their shape they will be found to be really pressing t'acmselves closer together by the efforts to take this form " c." The wooden pins and keys in the sleepers will, however, prevent this deformation, the only result being closer adhesion to planks, as form each of 11 to each other. Another plan of rail is shewn at fi. 3 the two side pieces overlap the joint of the middle raiTby half their whole length, and being secured with transverse pins and keys at the cross ties thus afford a continuous rail. Both these systems are without any iron work what- ever. ng. 3. before used, their convex iug taper at ould hardly ould be put their shape selves closer The wooden The compound rail, proposed by Mr. Ilulbert, is repre- sented at fig. 4 ; the bottom piece is 2 inches thick and 4 inches wide ; the upper or running rail 5 inches deep and 4 inches wide ; the ends of each of them overlap the other by half Its length, the two being bolted together at their ends by vertical wrought iron bolts. Objections were taken before the committee to the bolts being driven down through the f rail, as leaving the tops of them liable to be broken or er, prevent | loosened by the passage of the locomotive, but Mr. Ilulbert er adhesion | considered there was no danger of the top of the bolt bein. 12 broken off. " It would he driven down hy the loeight of the trains passing over it." Fig. 4. At some public meetings opinions adverse to tlie adoption of wooden railways have been expressed, but generally by persons who have had very little knowledge of the subject, and still less experience of the working of any system. Surely wooden railways, which in their most primitive form have rendered good service, are capable of improvement as well as iron ones, it being admitted beyond dispute, and acknowledged by men of position and experience, that they arc most suitable for and peculiarly applicable to the fulfilment of a great want in this country. Iron roads are beyond the reach of many districts ; wooden ones, answering all the purposes of iron ones, are within the reach of all, and improvements will take place in their construc- tion as the weak points shew tliemselves. It must, however, 13 bo borne in mind tl.at in the development of „l,„ost every meel,an.ea nnprovement, tl.ore is an increase in the „„n,I,er of part,, an. sueh e„m„licati„n aa is consequent „,,„n that crease -IheattentionanJohject of thei^proveris lo render then,achme more complete and better able to fulfil the pur- poses of the invention, and that which appears complicated to some, ,s reallj, very often only a repetition of parts held in their rcspect,ve positions by the simplest possible means. The breech-loader is a more eomplieated weapon than the old musket; and the spinning-wheel of our grandmothers was a ;2';;-.no than that Which the Whole world now use. I believe I have given a fair description of the different systems of wooden railways proposed. It is for those who are about to use them to select that which shall appear, under all arcun,stanoes, the most advantageous for colonization pur- poses. ^
