the warm air is conveyed, by means of flues, to the various rooms of the building, each flue being under the immediate control of the officers of the institution. Ventilation is obtained by flues communicating with the space just below the roof; and the impure air is expected to pass off through openings in the cupola which rises above the roof ridges. By the heating apparatus the danger and trouble consequent on numerous fires are avoided, at about the same expense which the common mode would cause. Very judicious arrangements for drainage, laying off the grounds, etc., appear to have been adopted, and are in progress. The building is to be approached by a gracefully curved carriage road. The grounds are to be surrounded by a hawthorn fence, immediately within which will be a shaded, thoroughly drained path for walking. The slopes of the hill in front are in course of levelling, and will soon present a scene of lawn and grain field; while a southwest area is laid off as an extensive garden and nursery of trees and shrubs. This important appendage to such an institution is charmingly situated, as regards scenery; and, with its terraces, plantation, vegetable and flower departments, etc., will soon be a very admirable place of resort for purposes of sanitary toil, or retirement and rest. We rejoice that, altogether, the establishment promises to be a very decided proof of provincial advance, and a credit to the country. After all the difficulties, delays and doubts that have occurred, this is a very gratifying result. The building is expected to be ready for reception of patients sometime in September, or the early part of October."--_Halifax Morning Sun_, _June 14, 1858_. * * * * * HALIFAX.--The following letter of a correspondent of the _New York Times_ may interest the reader.
