However, as the Congo State has planted a number of 
Funtumias, experiments are still carried on in order to improve 
the system of tapping. 
The different methods recommended in other colonies have 
been tried in the Government plantations: the Schulze im Hofe 
system (vertical incisions); the full herring-bone (15 to 20 ft. 
high); the Christy system (pricking on the herring-bone 
pattern). 
A new method has been devised by M. Sparano, one of the 
Congo Government Agriculturists. It is similar to the Christy 
method, but the full herring-bone is not made in one operation; 
the tapping is completed in nine or ten days, a few new laterals 
being traced every other day. 
The trees seem to stand this tapping very well and yield 
heavily, the yield in these experiments being twice the amount 
collected by the ordinary herring-bone, and four times the yield 
of the Schulze method. 
KAUTSCHUK-ANBAU IN DEN DEUTSCHEN KOLONIEN. 
Von Dr. Fritz FRAxk, 
Kautschuk-Zentrastelle fir die Kolonien, Berlin. 
[ ABSTRACT. ] 
Referent schildert die Verhaltnisse, unter welchen in den 
deutschen Schutzgebieten Kautschuk angebaut wurde und 
angebaut wird. Er zeigt, dass ausser den jeweils heimischen 
Gewachsen auch die unter anderen Verhaltnissen heimischen 
Kautschuklieferanten sich anpassen und verweist hier auf die 
plastischen Beispiele aus Kongo und Goldkiiste. Man hat dort 
die Hevea zum Teil auch unter Neiderschlags-Verhialtnissen, 
welche unter 2,000 m. liegen, heimisch machen kénnen und 
nach einigen schwierigen Jahren ungiinstiger Entwicklung den 
ortlichen Verhdltnissen angepasst befunden.

RUBBER CULTIVATION IN THE GERMAN COLONIES. 
The writer describes the conditions under which rubber is 
being and has been cultivated in the German Protectorates. 
He points out that, besides the original indigenous plants, 
rubber-y:elding plants which are native under other conditions 
also become acclimatized, and he refers in this connection to the 
examples from the Congo and the Gold Coast. There they
