Dr. A. W. 
.. 2 . 
have started north in the spring. 
Some years ago when I was working on the plants of 
lower California I was interested to learn that there is a 
South American creosote hush which I found by a comparison 
of specimens in the national Herbarium very closely resembles 
our own, but I had forgotten that it occurs so far south in 
that country. 
Your second shipment of specimens should be well on the 
way, and I trust it will not be so long delayed en route. 
Included herewith are several inclosures which are self- 
explanatory. An additional allotment of $600 will be made for 
your use during the third quarter of the fiscal year. Please 
return your expired identification card for cancellation. 
With best wishes for your continued success, I am, 
Sincerely yours.
