Some of them, of course, are cleverer than others.

The cleverest will remember the name of every plant in the garden, and will, perhaps, bring four or even six different kinds at a time; but generally we show them a leaf of the plant we want, or point out to them the bed where it is to be found, and do not trouble their memory with more than two different orders at a time.
