conducted us over the whole place with great civility and attention. [Illustration: THE FISHMARKET AT BALE.] [Illustration: GROUND-PLAN OF THE PISCICULTURAL ESTABLISHMENT AT HUNINGUE. Showing the disposition of the buildings and the situation of the experimental watercourses.] [Illustration: VIEW OF HUNINGUE.] The series of buildings which have been erected at Huningue are admirably adapted to the purpose for which they have been designed. The group forms a square, the entrance portion of which—two lodges—is devoted to the _corps de garde_, and the centre has been laid out as a kind of shrubbery, and is relieved with two little ponds containing fish. The whole establishment, ponds and buildings, occupies a space of eighty acres. The suite of buildings comprise at the side two great hatching-galleries, 60 metres in length and 9 metres broad, containing a plentiful supply of tanks and egg-boxes; and in the back part of the square are the offices, library, laboratory, and residences of the officers. Having minutely inspected the whole apparatus, I particularly admired the aptitude by which the means to a certain end had been carried out. The egg-boxes are raised in pyramids, the water flowing from the one on the top into those immediately below. The eggs are placed in rows on glass frames which fit into the boxes, as will be seen by examining the drawings. The grand agent in the hatching of fish-eggs being water, I was naturally enough rather particular in making inquiry into the water supplies of Huningue, and these I found were very ample: they are derived from three sources—the springs on the private grounds of the establishment, the Rhine, and the Augraben stream. The water of the higher springs is directed towards the buildings through an underground conduit, whilst those rising at a lower level are used only in small basins and trenches for the experiments in rearing fish outside. Being uncovered, however, they are easily frozen, and are besides frequently muddy and troubled. As a general rule, fish are not bred at Huningue, the chief business accomplished there being the collection and distribution of their eggs; but there is a large supply of tanks or troughs for the purpose of experimenting with such fish as may be kept in the place. The waters of the Rhine, being at a higher level than the springs, can be at once employed in the _appareils_ and basins. The waters of the Augraben stream, which cross the grounds, are of very little use. Nearly dry in summer, rapid and muddy after rain, they have only hitherto served to supply some small exterior basins. Of course, different qualities of water are quite necessary for the success of the experiments in acclimatisation carried on so zealously at this establishment. Some fish delight in a clear running stream, while others prefer to pass their life in sluggish and fat waters. The engineering of the different water-supplies, all of them at different levels, has been effectually
