Dubs, of Glasgow, and by Messrs. Nasmyth, Wilson,and Co., of Manchester. Fig. 10 is a woodcut of an engine in general use on the railways of New Zealand.* Itsweight in working order is 18 tons; it has six wheels 3 feet 6 inches diameter, and all is a highly efficient type of engine for steep gradients, the whole weight being utilized forgaining maximum adhesion. Further particulars are given in estimate No. LOCOMOTIVE IN USE ON NEW ZEALANH RAILWAYS. To go beyond these sizes would be to enter the region of full-sized railways and engines,the consideration of which is foreign to the present purpose. The object the author has inview is essentially cheap, small, slow-speed railways. Here it may be proper to remark, that care must be taken to guard against the error ofmaking small railways and then expecting them to do the duty of heavy ones. For example,to make a railway of 3 feet gauge and 10-ton engines, and then attempt to travel at 25 miles anhour, or to work a goods traffic with trucks which weigh 3 tons empty, is to mistake the wholenature of the subject. * New Zealand lias made more rapid progress in the development of light narrow-gauge railways than anyother colony. At the end of June 1876 there were 8G0 miles of railway open for traffic, and 367 miles inprogress. REMUNERA TIVE RAIL JVA YS
