A great deal also depends upon the exact position of buildings. Thus, to obtain the maximum of light in a factory, it will be obviously beneficial to erect it with the long sides running east and west, so that the windows face the north and south, and the large end doors face the east and west respectively. At first sight it would appear that the best position for the machines would be on the north side of the building where no sun can enter; but a moment’s consideration shows that the south side would give the best results. By the time the sun has come round to the south, it is usually high in the heavens, and the direct sunshine does not fall very far into the room. Even should it play upon the machines for an hour or two during the day, no harm could result to the rubber which was being worked, as no piece would remain there a sufficiently long time to be injured in the slightest degree. Placed in this position, the maximum benefit of light would be obtained, whereas if the length of the building ran east and west, the machines would have only either the morning or afternoon light.
While it is advisable to erect a factory running east and west, the drying-houses should run north and south. In this position the maximum wall area will be exposed to the sun during the day, and it will be possible to manipulate the windows of the drying-rooms so that those along one side are open, and it will never be necessary to close all the windows at any time of the day. Thus the windows facing east will be closed, and those facing west will be open until after midday; then vice versa. With such an arrangement a more uniform temperature may be obtained than by any other arrangement of the buildings. If the building ran east and west, the windows on the north side could remain open all day, while those facing south would have to remain closed practically all day. The south side of the house would be heated by the sun, while the north side would remain cool, and the rates of drying would be correspondingly unequal. The total wall area heated by the sun at any time of the day would be less in this position than if the house ran north and south.
Similarly, to obtain the best drying effect during the daytime in a smoke-house the building should run north and south. By this means the temperature will be maintained to the maximum possible by sun heat, and the rate of drying will correspond.
Suggested Arrangement of Building.

Drying-house No. 2 should be of two storeys, and unless a separate sorting and packing room is to be built, No. 1 should also have two floors (see [previous notes] on packing-rooms).
