AUGUST 24th, 1923 
My dear Lankester: 
Mason came to my laboratory on the 1 8th 
August, He shared with me many of the pleasant memories he b 
brought home from his brief visit to yon. His remarks about 
the opportunities for telling discoveries in the vicinity of 
Cartago made me restless, and my expressions of regret at our 
not having stimulated the interests of collectors in Costa 
Rieattouehed a very tender spot in his attitude toward the 
future. It is highly probable that Mr. Standiey will make 
concentrated efforts to extend our knowledge of the flora of 
your more prominent mountains and that he v.lll begin his work 
early next winter. In fact we are now convinced that no delay 
should be suffered 
Powell is diligent. His Indefatigable seal 
is one of the Joys in ray contemplation of Central American ore1 
dology. His specimens are often works of art. I assure you that 
for a self-trained worker in the technic of the herbarium he 
has made startling progress, I want tfi make his collection a 
creditable memorial to his enthusiasm, 
I enclose one of the labels that I had prin¬ 
ted for your Costa Rican set,I have five hundred of these labels. 
When may I expect the pleasure of ordering another supply? 
I am afraid that my boyish enthusiasm must 
seem to you inordinately intense, but I take courage in the thoufet 
that you have experienced similar enthusiasm among those flutter¬ 
ing things that seem to rival the orchids in beauty of color-pat^' 
terns, The collector's spirit, whether the hobby centers In plants 
or animals is specifically the same and the victims of it under¬ 
stand each other. 
Your specimen® have arrived from Washington, 
They made my day cheerful to the end, I wished there were more. 
But if you had sent ten times as many, I would still say that. 
The Kasdevallitt sent in your lei.ter of Aug. 
1st. is surely M, Heichenbachlana «T did not boil up the flower 
and will wait for more material before attempting a sure diagnosis. 
It hurts to mutilate anything in the category of uniguity. 
When may I expect the specimens that Jimenez 
has in hand? Row is the time to get this material under the lens. 
With the best - of good wishes, 
Yours faithfully,
