The position of the house with reference to the points 
of the compass has long been a question of argument. 
Many experienced growers positively claim that it makes 
no difference whether the house runs east and west or 
north and south. Houses running east and west admit 
more sunlight during the short days of the winter, while 
light distribution is more uniform in those running north

growers operating three-quarter-span houses, probably 
prefer buildings running east and west. Many growers

in the West prefer north and south houses because of the 
greater comfort in working in them in hot weather. 
Grading the land generally reduces the cost of con-

crops more convenient. Water is more evenly applied 
when the land is comparatively level, and uniform tem- 
peratures in all parts of the range are more easily 
maintained. 
Size and proportions.—Large houses have many ad- 
vantages. They are heated more economically, and the 
cost of operation is less than in a series of small houses 
of equal area. As previously stated, it is not uncommon
