In many districts special rates are offered where heating or cooking apparatus, or motors for pumping, etc., are used during the daytime, also for basement lights. So when arranging for a supply enquiry should be made as to terms. In the case of basement lights in small houses the saving is nearly all swallowed up in the extra meter rent, but in houses having large basements where it is necessary to use the lights for many hours a day the advisability of going on the special rate is a point well worth inquiring into closely. In spite of the extra hours necessarily burnt by basement lights, there is no doubt that great waste often occurs in the domestic offices--lights are switched on at dusk in passages, kitchen, pantry, and servants' hall, and even when all the servants are having supper in one room every light will be found alight in all the others. It is difficult to guard against this, but if a small notice is fixed to the wall above the switches asking that the light shall be turned off when not in use, it sometimes has the desired effect. These notices can be bought ready printed. Another source of waste which was never realised until the special constable came into being is in the servants' bedrooms. I am told by a member of that body that one of the things which has struck him more than anything since he took up his lonely patrol is the number of lights which are kept burning all night in the top rooms. This can be obviated by a master switch controlling the top floor, which can be in charge of one of the head servants. It is not advisable to have this in one of the lower bedrooms, as is sometimes done, as it necessitates the mistress waking up early in winter when lights are needed before breakfast, and, further, might lead to confusion in the case of a fire or illness in the night. It is impossible to lay down any definite rules for the lighting of the various rooms, as tastes differ so much as to the amount of light required; but whatever the individual taste may be, the naked lights should be so placed that they cannot be seen. This can be accomplished by well-shaded wall or portable lamps or indirect lighting. This latter form has much to commend it, as it is economical and gives an even distribution of light all over the room. When Putting in Electric Light. It is as well to err on the side of extravagance in the number of wall plugs. When the floor-boards are up it is not a very costly matter to have them put in, and then when the furniture of a room is altered from the position originally assigned to it, as is so often done with a new house, it will not be found that the writing-table or sofa is on the opposite side of the room to the plug to which the lamp required to light it is attached.
