Part III, on December 23, 1908; Chapter I, Part IV, on Septem- 

 ber 28, 1909, and the last sheet of the text on May 25, 1910. The 

 last galley proof of the index was mailed to Dresden on February 

 8, 191 1. The corrections, title page, table of contents and pref- 

 ace were received after the entire book had been printed, and 

 this statement refutes one of the points of criticism made by 

 Taylor. I received the first bound copy of the volume on June 

 8, 1911. 



Taylor mentions the fact that Hibiscus moscheutos occurs at 

 Spotswood, N. J., in the middle of the bed of Pensauken Sound 

 (notice the spelling in two places Penausken) is not well taken, 

 for the plant which I supposed followed the shore line of the 

 ancient sound might well have spread to the middle of the sound 

 as the waters gradually retreated. The note on page 197 of his 

 review is misleading, if the text is read again more carefully. 

 I do not say on page 372 of the book that Drosera rotundifolia, 

 Primus pennsylvanica, Fragariavirginianaare true alpine plants, 

 but give them in a list of the alpine plants of Mt. Katahdin. 



I am glad that Taylor has given his opinion of my volume of 

 Die Vegetation cler Erde, and I hope what he has said will 

 invite botanists to buy and read a volume which I trust will 

 take its place as a sound contribution to North American phyto- 

 geography.

[That I did not take into consideration the time necessary for 

 such a large work to go through the press is perfectly correct. 

 The dates given above by Professor Harshberger fix the time when 

 the book left his hands, information most welcome, — as there 

 is no indication of these important dates in either the preface 

 or title-page of the work.]
