To J. D. Hooker   19 August 1873

Down, | Beckenham, Kent. [Bassett, Southampton.]

Aug 19th 1873

My dear Hooker

The next time you walk round the garden ask Mr Smith1 or any of yr best men what they think about injury from watering during Sunshine.

One of yr men viz Mr Payne at Abinger, who seems very acute, declares that you may water safely any plant out of doors in sunshine, & that you may do the same for plants under glass, if the sashes are opened.2 This seems to me very odd, but he seems positive on the point; & acts on it in raising splendid grapes. Another good gardener maintains that it is only cold water dripping often on the same point of a leaf that ever injures it.. I am utterly perplexed, but interested on the point. Give me what you learn when you come to Down3

yours affectly | Ch. Darwin

I shd like to hear what plants are believed to be most injured by being watered in sunshine, so that I might get such. I expect that I shall be utterly beaten, as on so many other points; but I intend to make a few experiments & observations.— I have already convinced myself that drops of water do not act as burning lenses.
