Boarding houses lie midway between private houses and hotels, and so may perhaps be best considered in this chapter ; an example being illustrated in Fig. 19, which represents the Eversleigh Boarding House or Private Hotel, at
On the top floor the division is carried so far that bedroom No. 18, intended for the proprietor, has doors opening on to two corridors, one apportioned
to guests and the other reserved entirely for the servants. this may be done, it is necessary to provide some means by which the impure air may find its passage out. A foul-air shaft, taken from the ceiling to a ventilator of some description at ridge level, will
afford the necessary means of exit. One or more shafts may be used according to the size of the stable, but they should be taken from as central a position as possible, although, for economy of space in the usual loft above, it is found oftentimes convenient to place
the grating in a corner of the stable and to carry the shaft in line with the rafter. At the same time, it would appear wise to secure the best means of ventilation, even though it may mean some slight inconvenience. A fixed iron grating may be placed
at the mouth of shaft, or else it may be covered with mesh wire or perforated zinc and have a wood door fixed in grooves, sliding so as to leave ventilator
closed or open at will, and controlled by a rope and pull carried over a pulley and fixed at a convenient place. This is shown in Fig. 20, and is a very usual arrangement, but any other of the many systems of ventilation already described in full in Volume III. may be adopted.
