CANE SUGAR. 



In writing of matters which I can only hope to touch on as an amateur, there 

 is danger of serious error. I have been fortunate, then, in the opportunity of 

 having the earlier portion of my manuscript read by friends and colleagues, Mr. 

 C. F. Eckart, Dr. E. C. L. Perkins, Mr. L. Lewton-Brain, and Dr. H. L. Lyon ; 

 but of course the whole responsibility for the matter therein contained rests with 

 me. Those parts dealing with analysis were read over by Mr. S. S. Peck and 

 Dr. E. S. Norris, to both of whom I am indebted for several suggestions. 



To Mr. W. E. E. Potter and Mr. J. H. Wale I am indebted for the originals 

 of many illustrations, including those of the coloured plates of the Salangore and 

 the Purple Bamboo Canes, and of the coloured illustrations of insect pests, all of 

 which are the work of Mr. Potter. 



To the Experiment Station Committee of the Hawaiian Sugar Planters' 

 Association my thanks are due for the loan of the blocks whence are printed Figs. 

 2-8, 63, 69, 70, 72-76, 82, 83, 105, 126, 188-190; those drawings illustrative 

 of the anatomy of the cane were prepared under the direction of Dr. N. A. Cobb, 

 and admittedly form a series remarkable as an exhibit both of technical skill and 

 artistic merit. 



Messrs. Baird & Tatlock have supplied the blocks used in Figs. 237 and 246 ; 

 Messrs. Peters that of Fig. 238; Messrs. J. & J. Erie that used in Fig. 239; Messrs. 

 Watson, Laidlaw & Co. those used in Figs. 207 and 208 : Messrs. Pott, Cassels & 

 Williamson those used in Figs. 204, 206, and 209 ; Messrs. Bullivant & Co. that in 

 Fig. 93; Messrs. Zeiss that in Fig. 262; Mr.T. L. Patterson that of Fig. 212; Messrs. 

 Holden & Brooke that of Fig. 270 ; and the Eichardsoii Scale Co. that of Fig. 269. 

 Mr. J. B. Syme has supplied me with the originals whence Figs. 42, 88 and 98 

 were prepared. 



It will be seen that I have quoted largely from the published works of 

 Geerligs, of Went, of Kobus, of Harrison, of Eckart, and of Stubbs, to mention 

 only a few of my sources of information. No work on any subject could pretend 

 to completeness which failed to avail itself liberally of the results of the leading 

 investigators. 



I have departed from ordinary text-book conventionalism in inserting some 

 notes in the Appendix, amplifying certain points in the text. Owing to my 

 distance from my printers I received only a ' paged-out proof,' and it would 

 have been possible only at some considerable inconvenience to have then made 

 lengthy alterations in the body of the text. 



My thanks are due to Mr. Norman Eodger for the trouble he has taken in 

 seeing my manuscript through the press.
