where it is now considered an important forage plant. It was introduced into the United States about ninety years ago. The results of fifteen years' work at the Central Experimental Farm, Ottawa. favour its introduction into certain parts of eastern Canada.
Cultural conditions: In central Europe Sainfoin grows nat urally on dry, sunny hills, along borders of woods, etc., wherever the soil is rich in lime. Lime is necessary to its development and it can be successfully grown almost anywhere where the supply is sufficient. It should succeed in many districts of eastern Canada where there is a limestone foundation. It makes an excellent growth on a deep, porous, well-drained loam containing a fair proportion of lime. Heavy clays are less suitable as growth is generally too slow, and low-lying land covered with water during any part of the season is as bad as swampy land or land with a wet subsoil.
Climate: Sainfoin is best adapted to a temperate climate with a medium amount of moisture. On account of its deep root system, however, it is extremely resistant to drought and makes a surprisingly good stand when most other forage plants would suffer severely from lack of moisture. Once established, it stands the winters of the Ottawa valley fairly well.
Habits of growth: It is sometimes difficult to obtain a good stand of Sainfoin. The seed is often poor and yields only a small percentage of strong, vigorous plants. Needs are liable to crowd out young Sainfoin and it is important that the land be kept clean. When it is well established on suitable soil, it will produce crops for many years. In Germany it is by no means rare to find fields twenty years old. Tests at the Central Experimental Farm, Ottawa, however, indicate the advisability of allowing it to remain for three years only.
Agricultural value: It can be best compared with Alfalfa, but it has the advantage of making a better growth on poor land. Its name, which is of French origin and was originally written Sain foin,* means "Wholesome hay."
Fodder: Sainfoin should be cut for hay when in bloom. The stems get woody after flowering is over and the hay is poorer. Occasionally two crops can be taken the second year. After the last
* The name has sometimes be?n erroneously written Saint Foin and has thus led to the misconception that it means " Holy hay."
