great lord to whom the intendant finds it convenient to make his court. A great bridge cannot be thrown over a river at a place where nobody passes, or merely to embellish the view from the windows of a neighboring palace: things which sometimes happen, in countries where works of this kind are carried on by any other revenue than that which they themselves are capable of affording.
In several different parts of Europe the toll or lock-duty upon a canal is the property of private persons, whose private interest obliges them to keep up the canal. If it is not kept in tolerable order, the navigation necessarily ceases altogether, and along with it the whole profit which they can make by the tolls. If those tolls were put under the management of commissioners, who had themselves no interest in them, they might be less attentive to the maintenance of the works which produced them. The canal of Languedoc cost the king of France and the province upward of thirteen millions of livres, which (at twenty-eight livres the mark of silver, the value of French money in the end of the last century) amounted to upward of nine hundred thousand pounds sterling. When that great work was finished, the most likely method, it was found, of keeping it in constant repair was to make a present of the tolls to Riquet, the engineer, who planned and conducted the work. Those tolls constitute at present a very large estate to the different branches of the family of that gentleman, who have, therefore, a great interest to keep the work in constant repair. But had those tolls been put under the management of commissioners, who had no such interest, they might perhaps have been dissipated in ornamental and unnecessary expenses, while the most essential parts of the work were allowed to go to ruin.
