Co-operation means working together for the benefit of all. Without co-operation modern society could not exist. Co-operation has been at its best among the farmers in the dry areas of certain parts of Australia and Africa. The fields have been irrigated in these areas. Crops cannot be grown without water. For this purpose, canals and reservoirs have been built. The canals have been cut through the fields of not only one farmer. Those who live higher up the valley than the others have permitted canals to be built through their land in order to carry water to the fields of farmers lower down. When there is a long period without rain, all share the water. Instead of taking all the water for them selves, the farmers in the higher land leave enough water for their neighbours down the valley. Farming in the dry areas has been made possible by such co-operation. By co-operation farmers have learned to make even the desert produce crops.
In dry weather the farmers who live higher u

C. build canals across the fields of other farmers

Snow Ranger
The two things—snow and mountains—which are needed for a ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain—often called White Death.
It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937—1938 at Aha, Utah, in Wasatch National Forest.
This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a major ski area.
Thus, development of Aha and other major ski resorts in the west was dependent upon controlling the avalanche. The Forest Service set out to do it, and did, with its corps of snow rangers.
It takes many things to make a snow ranger. The snow ranger must be in ex
A. To make sure ski area operators are following safety rules.

C. To check skis and repair them.
D. To forecast the weather.
