My dear Hooker

Thanks for advice about Reversion & clearness. When I go over 1^st Ch. I will see what I can do.— But I hardly know how I am obscure; & I think we are somehow in a mutual muddle with respect to each other, from starting from some fundamentally different notions.—¹

Confound the Acacias, say I.— A very little experiment, would, I think be worth trying, if you have 2 trees of same species; take pollen from one, ((that grown under any to most different circumstances) & dust the stigmas well 2 or 3 times of same half-dozen or dozen flowers on the other tree at intervals of a day or two, & see whether that will improve the chance of setting seed.—²

I am very glad to hear that you will look to Goodenia.—³

Yours affect. | C. Darwin

The dusting with pollen sh^d. be done in morning.
