cinth culture assumed the same proportions and in a list of 1734 
similar to the tulip list above mentioned, a bulb of ‘“ Bleu Passe 
non plus Ultra” is said to have realized the sum of 1,600 florins. 
On the way to Leyden the train passed through miles of bulb 
fields where owing to the advanced season little was in bloom 
except the variously colored forms of the Spanish iris. New 
bulb storage houses can be seen in nearly every little hamlet, for 
bulb culture, especially tulip culture is again assuming a more 
and more important réle in European horticulture, a tendency 
that is being fostered perseveringly by the Dutch bulb growers. 
At Leyden I spent an afternoon and morning with some book 
dealers, resulting in the Garden acquiring some further eighty 
volumes, mainly works on East Indian botany and horticulture. 
An afternoon was devoted to the Botanic Garden where I had 
the pleasure of meeting the Director, Professor Janse, and, with 
r. Goethart, the conservateur of the Ryks Herbarium, was for- 
tunate in arranging a series of exchanges of both publications and 
Dutch East Indian herbarium specimens. Dr. Goethart, besides 
his duties at the Ryks Herbarium, is the Librarian of the Société 
Botanique de Leyde and we mutually agreed upon an exchange 
with that association by which we are to receive their A7vwid- 
kundig Archief for our Butterin. The great herbarium is 
mainly rich in types of all the older Dutch East Indian collections 
and is now undergoing an elaborate restoration, rearranging and 
numbering, under the able direction of Dr. Goethart who is 
building up a card index of every specimen preserved in the col- 
lection. The Botanic Garden is certainly one of the most ex- 
quisite and charming in Europe. Some of the trees are superb, 
notably a weeping beech (Fagus sylvatica pendula), which the 
Conservateur, M. Witte, who showed me through the planta- 
tions, told me was go years old. The great branches sweep the 
ground in all directions and are perfect to the very tips. The 
small Alpine Garden is a gem and at the nine of my visit was gay 
with clumps of the Alpine rose (Rkodod ferrug ) sev- 
eral dainty Saxifragas, Dianthus mon anus, Sedum ae 
dlrabis montana, and some lovely columbines. At the foot of 
the rockery in a small crescent-shaped pond, grew some very
