during the early fall. They do not need a large amount of water, 

 but should be given plenty of cultivation. Baking of the soil 

 about the plants is very injurious. 



Varieties. Green peas may be secured during April by 

 either of two methods : Early dwarf varieties may be sown dur- 

 ing midwinter, or larger later varieties ma}' be sown during the 

 previous fall. Some growers prefer one method and some the 

 other, while still others pursue both. The best dwarf varieties 

 for sowing from the latter part of December to the middle of Feb- 

 ruary are the American Wonder, Little Gem, Nott's Excelsior, 

 and Gradus. For sowing during late October, November, and 

 early December, the most popular varieties are the Yorkshire 

 Hero, Champion of England, Horsford's Market Garden, Strata- 

 gem and Telephone. For August and September sowing, to pro- 

 duce green peas during November, only the dwarf, early varieties, 

 like the American Wonder and Little Gem, are suitable. 



POTATOES. 



Culture. The season between the frosts of early spring and 

 the heat of early summer being short, the growing of potatoes dur- 

 ing spring is attended with difficulties; and greaier difficulty still 

 is encountered in attempting to grow them between the heat of 

 summer and the frosts of late autumn. But proper attention to 

 the requirements of this important vegetable results in a fair yield 

 during May and June, and a usually lighter one in November. 

 The potato requires a mellow, loamy soil kept moderately moist 

 — neither too wet nor too dry. A good percentage of humus in 

 the soil is also highly desirable. This condition may be secured 

 by turning under alfalfa, or by applying plenty of stable manure, 

 followed by deep plowing and thorough harrowing. 



For spring growth the best time to plant, according to our 

 experiments at the Station farm, is from the middle of January to 

 the middle of February, in the Salt River valley. The later they 

 are planted here after the middle of February, the less growth they 

 will make before the hot weather of June, which in the vicinity of 

 Phoenix, is sure to level all potato tops to the ground. The seed 

 pieces are commonly dropped 12 to 18 inches apart in furrows 2)4 

 to 3 feet apart, and covered by throwing a furrow over them. If
