When tepary seeds are placed in moist soil and the soil is 
pressed snugly about them, they will take up enough moisture t 
cause the skins to wrinkle within 5 minutes. When thrown in 
water, they will wrinkle within 3 minutes to a condition such as 
is assumed by the skin of the kidney bean only after 3-6 hours of 
soaking (fig. 11). 
b) When once the tepary has established itself in the soil, it is 
able to withstand protracted seasons of water famine without 
permanent injury. The ability to recover from the effects of

drought is not possessed by beans to a marked degree. This 
places them at a great disadvantage in a competition with the tepary 
under such conditions as are frequently met in the practice of dry 
farming. 
c) The tepary is inured to the greatest extremes of our summer 
temperatures and will bloom and set seed during any month from 
May to November. On the other hand, when the blooming period 
of beans happens to fall within the season of extreme heat, the buds 
will for the most part either abort before blooming or else the flowers 
will fall without setting pods. For these reasons the tepary 15 4
