[August, in the price of labour in excavations; and when it is considered tbat | points, crossings, and turn-outs, assume a place of greater importance the quantity of excavation on some lines extends to nearly 100,000 [ thau heretofore, and if you think them worthy of a place I will en- yards, the amount then lost was nearly £4000 per mile, or about the | deavour to furnish another paper exclusively devoted to their con- whole cost of the permanent way. This I think is sufficient to show , sideration. that this subject is worthy of attention in all future lines of road. Now that railways are being made single lines or partly double ; ' St. Aan't, O. T. THE STEAM EXCAVATING We have already had the pleasure of introducing this important machine to the public, and we now avail [ourselves of the opportunity of giving some further account of it. As is well known, it is of Ame- rican invention ; and this individual machine was imported from the United States, after having ben employed on a railway there, for the purpose of testing its capabilities in this country. It is now at work on the Eastern Counties Railway, about 20 miles from London, and is exciting much attention. In its present state, the machine is rather complicated, but it is susceptible of great improvement; and we have no doubt that any machines manufactured in this country will be much simplified. For this purpose it cannot be in better hands, the management of the patent being entrusted,to Mr. John Braithwaite, the .ngineer, whose mechanical attainments are well known to the public, and who is well qualified to turn a machine of this kind to the best account. We shall now proceed to describe the performance of the engine, having already given its working details, with an engraving in the Journal, p. 147, No.
