Holland, as is well known, is a country built upon marshes, which have been drained and filled in by the patient industry of many generations of workers. The land is consequently very low, almost perfectly level, and is covered by a network of canals. It lacks many of the features which make up the natural scenery of other countries,—mountains and ravines, rocks and rivers,—but it is, nevertheless, a very picturesque country. Artists love it for the quiet beauty of its landscape. Though this is not grand and awe-inspiring, it is restful and attractive.
