My dear Farrer
If you have an idle hour do look at 2 or 3 old flowers of Coronilla, especially any which you could see that Bees have visited. Look with rather high power & very good light at base of vexillum beneath the single stamen, & see if any trace of ruptured or bored cell. It seems possible (& the stage of probabilities is long passed) that bees may then bore a minute hole & visit very quickly the same orifice again & again.2
I am now become mad about drops of water injuring leaves. Please ask Mr Paine3 whether he believes from his own experience that drops of water injure leaves or fruit in his conservatories. It is said that the drops act as burning glasses; if this is true they wd. not be at all injurious on cloudy day. As he is so acute a man I shd. very much like to hear his opinion— I remember when I grew hot-house orchids I was cautioned not to wet their leaves; but I never then thought on subject.
I enjoyed my visit greatly with you, & I am very sure that all England could not afford a kinder & pleasanter host & hostess than you two were to us4

Here is a maxim for you “It is disgraceful to be beaten by a Coronilla.”
