Ever and very cordially yours,

Asa Gray.

TO GEORGE ENGELMANN.

May 18, 1859.

Well, even $10,000 a year is much better than nothing for the botanical establishment. I wish we had half of that....

If Shaw will be liberal in his establishment, why not turn over to him your general herbarium? If I had one I could have free access to always, I would 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....

As to your own herbarium, I think you are right for the present. Keep you own; arrange it on paper of the size of Shaw’s. But look to an eventual combination, 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 reside up there, throw physic to the dogs, or only take a share in consultations, and have time to do yourself justice in botany.
