are usually injured by autumn frosts are corn, sorghums, beans, cow- 

 peas, cotton, potatoes, and tomatoes. Those liable to injury by the 

 low temperatures of winter are peas, alfalfa, lettuce, strawberries, 

 dates, oranges, lemons, pomelos, and Eucalypts. 



The crops that are killejd or brought to maturity by the heat of 

 summer are small grains, clovers, Indian corn, flax, bush beans, 

 potatoes, summer squashes, cabbage, cauliflower, lettuce, spinach 

 turnips, radishes, onions, rhubarb, raspberries, currants, and goose 

 berries. In addition to the above the following are checked in their 

 growth by the summer heat: Beets, alfalfa, tomatoes, melons, 

 cucumbers, squashes, pumpkins, asparagus, strawberries, black- 

 berries, deciduous fruits, citrus fruits, and Eucalypts. 



WHAT MAY BE PLANTED AND WHAT MATURES EACH 



MONTH 



Believing that information as to what may be planted each 

 month with hope of success and what commonly matures each 

 month in the Salt River Valley, will be of value, especially to new 

 settlers, the following classified statement is inserted. In parts of 

 southern Arizona having a cooler climate, planting is done later in 

 the spring and earlier in the summer; and in the vicinity of the 

 Colorado, planting takes place earlier in the winter and somewhat 

 later in summer. In the first paragraph under each month is 

 given the list of the crops that may be planted, and in the second 

 paragraph those that mature or reach a stage suitable for use. 



It will be seen from what follows that the time for planting 

 the largest number of drops is during January, February, and Sep- 

 tember, and that the greatest number of crops mature during May, 

 June, October, and November. During May and December com- 

 paratively few crops are planted, and January and February are 

 the months during which comparatively few crops mature.
