I was accompanied by Mr. E. G. Arzberger of the Bureau 
of Plant Industry, U. S. Dept. of Agriculture, who furnished a 
high-grade film camera with which about fifty photographs were 
taken for the Garden collection. Mr. Arzberger’s botanical train-

Auguste Victoria, we proceeded to Hamburg where we arrived 
on the evening of July 20. Two days were spent at Hambur:

chimeras not yet described. At the present time additions 
are being built to the main building to provide for considerable 
expansion in practical and scientific research, and I was able to 
note the general arrangement of the new laboratories. 
In the greenhouses special study was made of the plan and

of its kind in existence. It contains between fifty and sixty 
species of liverworts and numerous species of mosses growing in 
profusion and luxuriance in pots and on the walls of the house. 
Observations were made on the treatment of various plants both 
in greenhouse and garden culture and of the various hybrids 
grown for exhibition. I may say that Dr. Winkler plans to 
provide at the Hamburg garden a botanical center for the 
exchange of exotic plants, especially of those from South America. 
The excellent shipping facilities of Hamburg gives the garden 
special advantages for a in this line which is it

From Hamburg we went i to Berlin on the late afternoon 
of the 22d. The greater part of one day was spent in a visit 
to the nurseries of L. Spath near Berlin. Here a number of 
hybrid trees and chrabe were seen and special notes taken of
