stable manure. Results thus far secured indicate that stable manures can be 

 displaced by commercial fertilizers containing similar kinds and amounts of 

 plant foods, and that nitrate of soda, the only fertilizer thus far tested in con- 

 nection with stable manure, can be so used at an increased net profit. A rota- 

 tion of manure in one year and commercial fertilizers the next year seems 

 advisable.

Progress and prospects of date palm culture, R. H. Forbes (Arizona Sta. 

 Bui. 60, pp. 433-437, fig. 1). — This paper consists of a popular summary of 

 experience gained in the planting and care of date palms in Arizona since the 

 establishment of the cooperative date palm orchard at Tempe in 1899. It dis- 

 cusses soils, localities, cutting and transplanting suckers, enemies, production, 

 varieties, and planting seed. The date palm is considered valuable not only for 

 its own products, but as a means of protection for less hardy plants. The 

 wholesale planting of date palms is not recommended, however, since the ques- 

 tion of varieties best suited to the region is still in its experimental stage.
