=40. Aquaria Makers.= One of the most innocent and pleasing amusements that has attracted attention for some time is the making of aquaria. The cases are formed of plate glass, square, oblong, circular, or any shape to please the fancy of the owner. The glass is tightly sealed when joined. The aquaria are of two kinds: one is formed of salt water, and contains marine plants and animals; the other contains fresh water, and such plants and animals as are found in rivers and smaller streams. They form a beautiful addition to a garden, conservatory, or drawing room. Rocks form the foundation, and the soil on them furnishes subsistence to the plants. Zoophytes, mollusca, and fish form the inhabitants of the aquarium. Insects also find a place in this miniature "ocean or river garden." The size for parlors is from one foot to three in length. The largest aquaria in this country are now on exhibition at Barnum's Museum, New York. "They comprise over one thousand specimens of living animals and vegetation. In these tanks the water is seldom changed, the natural operations of the plants and animals keeping it always pure." They are made to order in New York, and we think might afford a pleasant pastime to some, and pecuniary profit to others. A work giving directions for making them has been published in New York. The author is a Mr. Butler, who has got up the mammoth aquaria in Barnum's Museum. There are two establishments in New York where they may be ordered, and specimens seen. "Before we leave the margin of the sea, we must just glance at the smaller occupations pursued there by women. The most considerable of these was once the gathering and burning of kelp; but chemical science has nearly put an end to that. There is still a great deal of raking and collecting going on. In some countries half the fields are manured with small fish and the offal of larger, and sea weeds and sand. Then there is the gathering of jet and amber, and various pebbles, and the polishing and working of them. The present rage for studies of marine creatures must afford employment to many women who have the shrewdness to avail themselves of it."
