PORTABLE METAL FRAME AQUARIUM. A useful tank in all sizes and tlie only kind that is satisfactory for larger sizes above eight or ten gallons. and the larger ones are more expensive. For aquaria holding ten gallons and upward, the only type that can be used to advan- tage is that with metal frame. When well set up such a tank will last for years without leaking, and is easily reset, or can often be readily mended by running a little asphaltum, red lead or an aquarium cement in the joints. The rectangular, straight-sided, all-glass jars, holding up to eight or ten gallons, are excellent; better in some respects than those with metal frames, for they are not hkely to spring a leak. The glass jars, however, are more likely to crack and so prove an extra expense, but in the hands of the experienced aquarist they are perhaps the most satisfactory kind for sizes under five gal- lons. Care should be taken to see that such jars rest firmly and evenly upon their bases, and that they are not subject to sudden changes of temperature. It is well to place an asbestos mat, or a pad composed of a few layers of blotting paper, under the jar to act as a shock absorber and to distribute the weight more evenly. The cylindrical jar with straight vertical sides is satisfac- tory to maintain, but the inmates appear somewhat distorted
