Vlll PLANTS BAKERIAN^E. 



The field work, all done between June 1st and September 

 1st by one person, resulted in the collection of above 25,000 

 specimens with notes on each species. Also, photographs 

 were taken of all the characteristic ecological associations. 

 As r ip ^previous years the work would have been largely 

 impossible put /or the co-operation and encouragement of 

 ,J)r.; 15.; L. ^Greene, whose remarkable knowledge of the 

 American field directed operations in these most remote 

 localities, even to definite hills, valleys and meadows. 



Here also should' be acknowledged the great kindness of 

 Mr. E. T. Jeffery, President of the D. & R. G. System, and 

 of other officials of the Road, without whose assistance some 

 of the work would have been quite impossible. A faithful 

 boy, Ed. Dundin, did the camp work, and most of the 

 changing of driers, though the work of first, putting plants 

 into press, taking out those finally dried, cleaning, bundling, 

 writing labels and separating a study set, necessarily de- 

 volved on the collector.
