224 NATURE-STUDY REVIEW [17:5— May, 1920 



very limited area of some five miles square. With it are associated 

 such other limited groups as the Bishop's Pine, the Knot Cone 

 Pine and the Monterey and Gowen Cypress growing near the sea- 

 coast in small isolated groups. 



The Monterey Cypress is, however, the tree which has attracted 

 most attention on account of its picturesquely grotesque outline 

 as it grows clinging to the outermost land limits of the coast. 

 It is never found more than 350 yards from the ocean where it 

 grips the cliffs in a desperate struggle with the violent storms which 

 break on the coast rocks. Here this tree, remnant of perhaps 

 vast forests of ages past, has taken its last stand. Unable to 

 survive and spread its kind unaided, yet the Monterey cypress is, 

 perhaps, the best known tree of California as it has lent itself 

 readily to cultivation and through man's aid is spread throughout 

 the world. It is used as an ornamental tree, hedges, or windbreak. 



To the soutr; we find near San Diego an interesting island of 

 Torrey Pines found nowhere else on the main land and only one 

 other group is known to exist and that is on the Island of Santa 

 Rosa off the coast of Santa Barbara. The giant trees of California 

 are too well known to need mention here and truly they are worthy 

 of the admiration of every tree lover the world over. 



Why should we as nature lovers be interested in these isolated 

 groups? For themselves they deserve our attention for the light 

 they throw on the geological history of our coast, and even though 

 they are Californian they belong to the wealth of the world. 

 They are protected for your joy as well as ours by the State and 

 Nation and all too often the hurried tourist misses them just 

 because no one told him they existed. You know now of some 

 of our tree islands, come and see them for yourselves. 



Mt. Lassen 



Calley Boyle 



Stately and haughty in her unique position as the only active 

 volcano on the North American continent, stands Mt. Lassen, 

 with her perpetually snow-crowned crest towering above her 

 green clad neighbors of the Sierra Nevada Range. Perhaps 

 less beautiful or of less stature than Mt. Shasta, her neighbor on 

 the northwest, yet she enjoys this distinction which makes her 

 the most interesting point in northern California.
