In these prosperous times when rubber profits are calculated by 
hundreds of dollars per acre, the discussion of an additional profit of 
$7 per acre may seem trivial, but since the seed cannot be allowed 
to remain in the ground and must be removed, some steps must 
be taken to deal with it. When a constant and large bulk of rubber 
seed is sent to Europe it is possible that the price of this 
commodity may increase very considerably and become an item of 
importance in the profits of a Rubber Estate. 
The value of the seed for cattle cake has not yet been estimated** 
the seed is greedily eaten by animals and has a high nutritive 
figure. 
Consignments of the present crop decorticated and with the 
shell on are being sent home by the pepartment of Agriculture 
and the market values and condition of these on reaching Europe 
will be made the subject of a further note.

GUAYALE RUBBER. 
A short time ago the home papers had paragraphs about a new 
rival of Para rubber planting in the shape of Guayale Rubber which 
has come into considerable prominence within the last couple of \ ears. 
The following notes may allay fears and are of interest, they are 
chiefly obtained from important article by Dr. R. EndLICH, on the 
present position and outlook of the Guayale industry in the July 
number of the Tropenpflanzcr , the organ of the German Colonial 
Economic Committee. 
The source of Guayale is “ Parthenium argentatum A. Gray,” a 
shrub, with an average height of two feet, growing on the plateaux 
of Mexico. It appears to thrive best in a dry climate and on soils 
containing a good deal of lime; in fact it is doubtful if it is suited
