ET. 48.] TO GEORGE ENGELMANN. 453 
not take the expense and trouble of keeping up and 
increasing one myself. . . . 
So, you have made the capital discovery, and proved 
the so-called Anthephora to be the female of Buffalo- 
grass. I would not have believed it without direct 
evidence. 
I cannot study it; it would take me a long while to 
get the case so before me that my opinion about the 
affinities of the grass would be of any use; but it is 
most interesting, and I beg you to work it out in 
detail and thoroughly. . . . 
June 6. 
As to your own herbarium, I think you are right 
for the present. Keep your own; arrange it on paper 
of the size of Shaw’s. But look to an eventual combi- 
nation, either in Shaw’s lifetime or soon after, and be 
open to propositions from Shaw; as, for example, to 
take your whole herbarium, provide for maintenance 
and increase, and when ready, to make you director of 
the whole concern. This duty must devolve upon you, 
and when it does, with a decent salary, you could re- 
side up there, throw physic to the dogs, or only take a 
share in consultations, and have time to do yourself 
justice in botany. 
Meanwhile, if Shaw would take your herbarium 
upon proper terms, you might at any time have any 
particular families of plants with you, in your house, 
to work at... . 
Mr. Shaw has lately written. I inclose his letter to 
you. I have just replied to it, expressing a lively in- 
terest in his projected establishment, and offering my 
best services if he requires them in the way of advice 
or suggestion. I hope it will be all right in the 
eng, .. .
