The price of the product also has a great influence on success in 
hay farming. Before the considerable expansion of the area in alfalfa 
in Arizona due to increased water supply, and while the Reclamation

Service was actively engaged in operations requiring a large amount 
of team work, the demand for alfalfa hay was strong and prices were 
comparatively high, but about the close of the year 1913 prices 
dropped to low figures and remained low through 1914 and 1915. 
The market was again stimulated in 1916 by the presence of United 
States troops on the Mexican border and prices rose to an abnormally 
high figure. Comparatively high prices were obtained late in the 
season of 1915 and early in the season of 1913, so that a considerable 
range in price is represented in the records used for this study. The 
price is also affected by the manner of curing and handling the hay, 
those farmers who cure in cocks (see fig. 6) and handle with pitch
