PREFACE TO PART X. 



In Part X, AMERICAN WOODS, we have a continuation of the trees 

 of the Pacific Slope, the fifth installment of the species of this region, 

 and taking up certain trees of special interest. "We are particularly 

 pleased to bring out in it sections of the singular Saguaro or Giant 

 Cactus of the arid regions, which always impresses travelers in crossing 

 the arid regions of the southwest. It was with considerable scepticism 

 that a trunk was felled and material taken from it for this use and 

 great was our surprise at finding that we could make and preserve 

 very satisfactory sections. We deem it best, however, to protect 

 them with mica in the mounted frames. We trust our patrons will 

 share with us pleasure in being able to see in these sections the inter- 

 esting structure of these strange trunks. 



We regret some delay in the appearance of Part X, occasioned by 

 demands upon the writer's time for attention to TREE STUDIES the 

 companion work to AMERICAN WOODS (taking up illustrations of the 

 trees, their characteristic barks, leaves, flowers, fruit, etc.), as per 

 announcement which was made with Part IX. Much work has been 

 done in connection with that with results which we trust will please 

 those who have expressed a desire for its appearance. 



In the preparation of AMERICAN WOODS Part X, I wish to grate- 

 fully acknowledge assistance and courtesies extended by Prof. Willis 

 L. Jepson, of the University of California, Mr. Chas. II. Shinn, Mr. 

 A. J. Johnson, Mr. A. L. House, Professors E. H. Forbes and A. J. 

 McClatchie of the University of Arizona, Prof. Wm. R. Dudley of 

 Stanford University, and last but by no means least Mr. and Mrs. Theo. 

 Hampe, whose sequestered home is among the Chiricahua Mountains 

 of Arizona and in the vicinity of which several of our wood specimens 

 were gathered. 



A General Index to Parts I-X is inserted at the close of this text.
