A large number of vacant places in both the Yuma and Tempe 

 Orchards were set with palms during the summer. The off- shoots 

 used in the Yuma Orchard were taken directly from the trees, being 

 too large to place in the propagating house, whereas those used 

 in the Tempe Orchard were rooted. Upon examination in Novem- 

 ber, 52 of the 81 plants set in the Yuma Orchard were showing 

 signs of growth. The Tempe planting is interesting from the fact 

 that the soil in the orchard is at present extremely alkaline. While 

 the older trees do not appear to be disturbed by the presence of 

 alkali, it was feared that the young plants probably would not fare 

 so well. As a precaution, therefore, about a cubic yard of sweet 

 soil was placed in the holes prepared for the off-shoots and a heavy 

 straw mulch applied to prevent the rise of the alkali. No ill effects 

 from the alkali have yet been observed, as the majority of the plants 

 give evidence of growing. 



A rather unusual feature of blossoming was observed at the 

 Yuma Orchard, in that certain varieties failing to bloom during 

 their normal blossoming period in the spring, flowered most pro- 

 fusely towards the latter part of the summer. A number of the 

 blossoms were pollinated in order to study the future behavior of 

 the fruit, particularly as to its ability to stand thru winter.
