It is a singular fact that the large towns of Holland have remarkably regular forms, although they were built on unstable land and with great difficulty. Amsterdam is a semicircle, the Hague is a square, Rotterdam an equilateral triangle. The base of the triangle is an immense dyke, protecting the town from the Meuse, and known as the Boompjes, which in Dutch means little trees,--the name being derived from a row of elms that were planted when the embankment was built, and are now grown to a great size. Another large dyke, dividing the city into two almost equal parts, forms a second bulwark against the inundations of the river, extending from the middle of the left side of the triangle to the opposite angle. The part of Rotterdam which lies between the two dykes consists of large canals, islands, and bridges: this is the modern town; the other part, lying beyond the second dyke, is the old town. Two large canals extend along the other two sides of the city up to the vertex, where they join and meet a river called the Rotte, which name, prefixed to the word dam, meaning dyke, gives Rotterdam. When I had thus performed my duty as a conscientious traveller, and had observed a thousand precautions against defiling, even with a breath, the spotless purity of that jewel of a room, I entered my first Dutch bed with the timidity of a country bumpkin. Dutch beds--I am speaking of those to be found in the hotels--are usually short and wide, with an enormous eider-down pillow which would bury the head of a cyclops. In order to omit nothing, I must add that the light is generally a copper candlestick as large as a plate, which might hold a torch, but contains instead a short candle as thin as the little finger of a Spanish lady. In the morning I dressed in haste, and ran rapidly down stairs. What streets, what houses, what a town, what a mixture of novelties for a foreigner,--a scene how different from any to be witnessed elsewhere in Europe! First of all, I saw Hoog-Straat, a long straight roadway running along the inner dyke of the city.
