CHAPTER IV
RAILWAY-CONTROLLED CANALS
Both canals and railways were, in their early days, made according to local conditions, and were intended to serve local purposes. In the case of the former the design and dimensions of the canal boat used were influenced by the depth and nature of the estuary or river along which it might require to proceed, and the size of the lock (affecting, again, the size of the boat) might vary according to whether the lock was constructed on a low level, where there was ample water, or on a high level, where economy in the use of water had to be practised. Uniformity under these varying conditions would certainly have been difficult to secure, and, in effect, it was not attempted. The original designers of the canals, in days when the trade of the country was far less than it is now and the general trading conditions very different, probably knew better what they were about than their critics of to-day give them credit for. They realised more completely than most of those critics do what were the limitations of canal construction in a country of hills and dales, and especially in rugged and mountainous districts. They cut their coat, as it were, according to their cloth, and sought to meet the actual needs of the day rather than anticipate the requirements of futurity. From their point of view this was the simplest solution of the problem.

But, though the canals thus made suited local conditions, they became unavailable for through traffic, except in boats sufficiently small to pass the smallest lock or the narrowest and shallowest canal en route. Then the lack of uniformity in construction was accompanied by a lack of unity in management. Each and every through route was divided among, as a rule, from four to eight or ten different navigations, and a boat-owner making the journey had to deal separately with each.
The railway companies soon began to rid themselves of their own local limitations. A "Railway Clearing House" was set up in 1847, in the interests of through traffic; groups of small undertakings amalgamated into "great" companies; facilities of a kind unknown before were made available, while the whole system of railway operation was simplified for traders and travellers. The canal companies, however, made no attempt to follow the example thus set. They were certainly in a more difficult position than the railways. They might have amalgamated, and they might have established a Canal Clearing House. These would have been comparatively easy things to do. But any satisfactory linking up of the various canal systems throughout the country would have meant virtual reconstruction, and this may well have been thought a serious proposition in regard, especially, to canals built at a considerable elevation above the sea level, where the water supply was limited, and where, for that reason, some of the smallest locks were to be found. To say the least of it, such a work meant a very large outlay, and at that time practically all the capital available for investment in transport was being absorbed by new railways. These, again, had secured the public confidence which the canals were losing. As Mr Sandars said in his "Letter":—
