It was while we were depending exclusively upon this expensive and tedious system of conveyance, when the internal development of the country was rendered all but impossible by the heavy expense of bringing produce to the sea, and when our export trade was consequently of the most restricted dimensions, that canals came to the rescue. They worked a marvellous change in the trade of the country—a change which can, perhaps, be best illustrated by the ordinarily dry, but in this case almost thrilling, returns of our exports and imports. Burke, in one of his greatest speeches,[26] spoke of a total exportation of the value of 14½ millions, and a total importation of 9½ millions sterling, as an index of extraordinary prosperity. In another equally great oration[27] he said, speaking of the fact that we were then exporting rather over six millions a year to our colonies, that “when we speak of the commerce with our colonies, fiction lags after truth; invention is unfruitful, and imagination cold and barren.” What would he have said had he lived to see, as we have done, our exports reach the vast total of 250 millions a year, with nearly 90 millions of exports to our colonies? Canals certainly did not complete this revolution, but they had a very important share in giving it a start. Between the time when the canal system was commenced, about 1760, and the end of the first canal period, which may be put at 1838, the export trade of the country advanced from 14 millions to about 50 millions per annum. This is poor progress, compared with what has since been attained, through the development of the steamship, the railway, the telegraph, and other modern adjuncts of commerce, but it was deemed as remarkable for that day as we consider our subsequent progress to be in ours.
