Preface 



strictly in accordance with the Vienna Rules, in so far as 

 these have been worked out in Canada. 



Plants will be found to vary greatly in size and appear- 

 ance at various altitudes, becoming smaller and shorter as 

 the summit of the mountain is approached, until at 7,000 

 or 8,000 feet one will find the tiny leaves of the Moss 

 Campion and Mountain Saxifrage growing flat upon the 

 ground, their starry blossoms having no perceptible stalks, 

 but being set close down into the moss-like plants. The 

 Speedwell, Mouse-ear Chickweed, Alpine Azalea, Whitlow 

 Grass, Eriogonum, Androsace, Saxifrage, Gentian and 

 Stonecrop are all in evidence at very high elevations, grow- 

 ing in dwarfed alpine forms, and, together with the Heath, 

 Heather and Anemone, are amongst the last flowers found 

 at the edge of perpetual snow. 



For his valuable assistance in preparing this book I offer 

 my sincere thanks to Professor John Macoun, to whom I 

 owe a debt of gratitude, beyond all' repayment, for years 

 of kindly help and encouragement. To Mr. James M. 

 Macoun I also offer my hearty thanks for his expert advice 

 given at all times with kindest courtesy. 



To Sir Thomas G. Shaughnessy I am very deeply indebted 

 for the interest he has always taken in my work among the 

 mountains, which has led to the writing of this book.
