ing and dying next
year, and the size of roots is generally proportioned to the life of
plants; except when artificial cultivation develops the root specially,
as in turnips, etc. Several of the Draconidae are parasites, and suck
the roots of other plants, and have only just enough of their own to
catch with. The Yellow Rattle is one; it clings to the roots of the
grasses and clovers, and no cultivation will make it thrive without
them. My authority for this last fact is Grant Allen; but I have
observed for myself that the Yellow Rattle has very small _white_
sucking roots, and no earth sticking to them. The toothworts and broom
rapes are Draconidae, I think, and wholly parasites. Can it be that the
Red Rattle is the one member of the family that has 'proper pride, and
is self supporting'? the others are mendicant orders. We had what we
choose to call the Dorcas flower show yesterday, and we gave, as usual,
prizes for wild flower bouquets. I tried to find out the local names of
several flowers, but they all seemed to be called 'I don't know,
ma'am.' I would not allow this name to suffice for the red poppy, and I
said 'This red flower _must_ be called _something_--tell me what you
call it?' A few of the audience answered 'Blind Eyes.' Is it because
they have to do with sleep that they are called Blind Eyes--or because
they are dazzling?"

20. I think, certainly, from the dazzling, which sometimes with the poppy,
scarlet geranium, and nasturtium, is more distinctly oppressive to the eye
than a real excess of light.

I will certainly not include among my rescued Draconidae, the parasitic
Lathraea and Orobanche; and cannot yet make certain of any minor
classification among those which I retain,--but, uniting Bartsia with
Euphrasia, I shall have, in the main, the three divisions Digitalis,
Linaria, Euphrasia, and probably separate the moneyworts as links with
Veronica, and Rhinanthus as links with Lathraea.

And as I shall certainly be unable this summer, under the pressure of
resumed work at Oxford, to spend time in any new botanical investigations,
I will rather try to fulfil the promise given in the last number, to
collect what little I have been able hitherto to describe or ascertain,
respecting the higher modes of tree structure.
