Both these drawbacks were present, nevertheless, to a serious extent, and for the same reason; the total absence of regulation of the flow of water. Locks, or "sluices" as they were termed then, were being introduced exceedingly slowly; how slowly is evident from a Frenchman explaining[34] the working in detail in his journal (without the use of any specialised terms) of one on the Reno, between Bologna and Ferrara. Considering that he must have had much experience of France and had by that time traversed all the waterways generally used for passenger traffic in Italy, it may be concluded that locks were at least very rare in both countries. Some such deduction may also be made for England and France from an Englishman doing the same when at Montargis on the Loire, nearly seventy years later.[35] Even in Holland, the nursery of the lock-system, its development was slow. In 1605 a Venetian ambassador mentions that the lock-gates between Brussels and Antwerp were only opened once a week, when the weekly trade-barge went along; at other times every one had to change boats at every lock; just as was done on the series of canals formed out of the marshes between the Reno and the Po, according to the Frenchman just quoted. In the middle of the seventeenth century, the same arrangement was in force between Antwerp and Brussels, so Evelyn says, whereas, he implies that between Bologna and Ferrara a lock system was fully in use. In canals, the great achievement of the period was the cutting of one for nine miles between Amsterdam and Haarlem in six months at a cost of £20,000, finished not long before Sir W. Brereton passed through it in 1634; the previous route had been by a canal in the direction of Haarlem Meer, the boat having to be lugged by hand past the dam which separated the canal from the Meer. Here, in Holland, too, was by far the best passenger service in Europe; in many cases boats were towed, or sailed, between town and town every hour with fares fixed by the local authorities, and the only complaint that is to be heard concerns the drunkenness of the boatmen, who frequently landed the passengers in the water. But there is an isolated complaint, by an Italian chaplain, which shows what the others accepted as no more than reasonable. Nearing Amsterdam, he and his passed the night in the open barge, unable to sit up, much less stand, because of the lowness of the bridges, but forced to lie, in pouring rain, on foul straw, as if they were "gentlemen from Reggio," a phrase that is still used in Venice as a synonym for pigs. Practicability, comfort, cheapness, and speed—for all these qualities the water could more than hold its own against the land under even conditions; and a traveller from Italy to Munich finishes his journey by raft down the Iser and reckons himself a gainer in time by using that means in preference to horseback.
