2. ARCHITECTURAL FISH POND AT THE VILLA STRADA, NEAR ROME. 
of tiles, with cement between the layers, will make a more complete job, but one layer is sufficient; 
the bottom must then be covered with tiles laid in cement in a similar manner, and the whole left till 
perfectly dry; the ornamental moulding may be formed, in bulk, by a single row of bricks, which, 
being covered with a sufficient coating of cement, may have moulding lines run along it with a mould¬ 
ing tool, in the usual manner known to any plasterer. The parts designed for the entrance and exit 
of the water may be formed in the same manner as the cement coping, and with but little more 
complication. The pipe conveying the water from the spring will be conducted to a small reservoir 
immediately behind the point at which it enters the tank, or to a leaden shape made to spread it into 
a thin semicircular sheet, in which form it will fall into the tank, as above described; the surplus 
water at the other end need only be conveyed away in a common brick drain; but, if desirable not to 
waste any of it, the drain should be lined with cement. Ornamental balls, vases, or other decorations, 
required, may be procured at little cost at any cement works, and can be easily added in the way 
of embellishment. 
I he tank being complete in all its parts, and the cement perfectly dry and hard, the aquatic plants 
may be placed in the vessels shown at A and B, which are intended to be rather more massive, and 
more broad in proportion to the height, than common flower pots, in order to keep them steady and 
secure at the bottom of the water. These pots, with their plants and soil secured by the perforated 
lids, may now be placed in the desired positions about the bottom of the tank; the Water Lilies, both 
white and yellow, and other plants, which grow commonly from a considerable depth, in the central 
compartment, and the Arums, and different species of Water Iris, &c., &c., in the shallower compart¬ 
ments at the sides. The best time for making a tank of this description is either at the end of March 
or late in September ; in the first place, to secure the cement from the effects of frost, which, before it 
is thoroughly dry, would cause it to become rotten and crumble ; and, in the second place, in order to 
place the plants in their new position after they have finished their summer growth, and are about to 
enter into their natural period of repose, or just before the spring growth commences. If it is found 
inconvenient to get the vessels for the plants made in the form suggested, ordinary flower-pots, with 
moderately-sized stones or pieces of tile placed on the surface of the soil to secure it, will answer the
