LETTER FROM PROF. S. B. GREEN 251 
each show in the flowers of this tree. It is not uncommon to see on a 
good specimen that appears perfectly yellow at first sight a few branches, 
or even buds, bearing lavender flower clusters, and on the same branch 
alternate flower clusters may be of different colors. 
In Bonn ve visited the house where tle great musical composer, Bee- 
thoven, was born. It is now preserved as a museum and is quite «an 
humble affair. Here is, perhaps, the finest avenue of horse chestnuts to be 
seen in the world. It is known as Poppelsdorfer Avenue. It consists ot 
two rows of trees on each side of a grass plat about 200 feet wide. The 
avenue must be at least a mile long and leads from the town to the botani- 
cal garden and the agricultural school and is exceedingly well kept up. 
From Bonn we went up the Rhine to Bingen and Rudesheim, and to 
Weisbaden, where we passed the night. Here we saw the kaiser. He is a 
sensible looking man and much better than his pictures represent him to be. 
This is a fashionable watering place and very beautiful and noted for its 
hot springs, which are celebrated for their curative properties for rheu- 
matism and gout. My wife had thought that perhaps she had better 
remain here instead of in Heidelberg, as we planned, while I was in the 
Black Forest country, but a drink of the water convinced her that the 
remedy was worse than the disease, and we went on as planned. The 
water is about lukewarm and tastes of common salt and perhaps medicinal 
salts or Glauber’s salt. I felt something as it has been said that Nebuchad- 
nezzar felt when turned out to grass: “and murmured as he cropped the 
unwonted food, ‘It may be wholesome, but it is not good.’”’ I had rather cure 
my rheumatism by a good sweat than at Wiesbaden. I have gotten 1aany 
notes of interest that I propose to work over for the Horticulturist when 1 
have a little time, but at present I am too busy to do the subject justice. I 
have left Mrs. Green in Heidelberg for ten days while I am in th2 forests 
and am now spending my time walking and note-taking in the forests with 
a party of seven students in forestry who are here with Dr. C. A. Schenck, 
the forester of the Yanderbilt estate. Mr. E. L. Reed, of Anoka, with his 
son and Prof. Mason, of Berea, Ky., are also in the party. When through 
here we go from Carlsruhe to Munich, where are very interesting forests. 
I think I shall-be able to write you again before the horticultural meeting 
comes off. But in any event. I want to be remembered to the socety. with 
best wishes for a cordial hand-shake in the spirit for each and eve~y mem- 
ber and to our interested guests. I hope the meeting will be a delightful 
one and would like much to be with you. Cordially avd faithfuliy vours, 
Samuel B. Green. 
P. S.—In Giessen is a celebrated forestry school, in which I am much 
interested, and we have received many courtesies from the pr¢tfessors 
and students. We have been here two and one-half days and now go to 
Alsfeld.-—G. 
The Striped Cucumber Beetle is most effectively controlled by the use 
of Paris green when the insects are on the surface of the leaf. Kerosene 
emulsion and pyrethrum have been used with good results. The wild cu- 
ccumber can be planted as a trap crop, as the beetles seem to be very fond 
of it.
