The cool temperature by which the ice must be surrounded, to make it keep, has suggested the idea of forming niches or shelves within the ice-house, or in the passage leading to it, for keeping articles cool in the summer season. This has been tried with great success in the esse of common ice-houses; and it would in all probability succeed in the ease of ice-cellars, though the difficulty in this last case would perhaps be increased from the want of ventilation. We have already, in this work, expressed our opinion, that it would be more convenient to have the place for keeping the ice connected with the dwelling-house, either as a cellar under- the living-rooms, or as a cellar under some of the out-door offices, and to place it under the care of the butler, than to form it in the park or pleasure-grounds, and place it under the care of the gardener. However, as the common prejudice is in favour of ice-houses built in the usual manner in the open grounds, we shall here describe one of these formed according to the best principles.
