The seeds I put loose in this sheet are Cinchona officinalis. Get the tree introduced into your cooler region, that is, the Caffetals of east Cuba, and the tree will be commercially important in time, and you will be a benefactor of your species. Enough for once.
Ever your old friend,
A. Gray.
TO GEORGE ENGELMANN.
November 20, 1866.
Dear Engelmann,—Yes, I have a heap of unanswered letters from you. But I have not one moment of time.
I have copy of “Manual” in printer’s hands up to Compositæ, and am only now two days ahead; have been only two hours ahead day after day!! It is awful! So much other work too!...
If I could get five hundred to one thousand more a year I would at once resign professorship and salary....
I am well, never more hearty; but worked like a coach-horse. I have got my fund raised for the Garden: small, but we have now clear $2,500 or $2,600 a year for Garden.
February 27, 1867.
How much I am indebted to you! No one else who undertakes to help me ever makes out much, at least to save me time and trouble....
