Sixty-thfee people gave botanical specimens whose names and number 

 of specimens will appear on the list of accessions. 



A botanical excursion was made in April to the Grand Canyon and over 

 the Apache Trail from Phoenix to the Roosevelt Dam. The specimens 

 collected, representing 349 numbers and numerous duplicates, have not yet 

 been fully studied and are still unmounted and not incorporated in the 

 herbarium. They will form the basis of a paper on the flora of the Grand 

 Canyon which I hope to prepare. 



In July Mr. and Mrs. Charles E. Miller invited me to accompany them 

 on their yacht "The Yankee" to Santa Cruz and Santa Catalina islands. 

 Owing to the extreme dryness of the season the collection of 165 numbers 

 consisted chiefly of the woody plants since there was scarcelj^ even a trace 

 left of the herbaceous vegetation. 



Mr. Wm. F. Herrin invited me to a week-end trip to Shasta Springs in 

 September, and even at that late time 79 numbers were added. 



Another week-end trip in October to the Pinnacles in San Benito County 

 as the guest of Mr. and Mrs. G. Earle Kelly added 38 woody plants to the 

 collection and some duplicates.
