and adds: "Less poetical, but as graphic, was a Devonshire woman's comparison of a dull preacher to a 'Drummle drane in a pop;' Anglicè, A drone in a foxglove,--called a pop from children amusing themselves with popping its bells." The prettiest of all humble roadside flowers I saw was the little blue speedwell. I was seldom out of sight of it anywhere in my walks till near the end of June; while its little bands and assemblages of deep blue flowers in the grass by the roadside, turning a host of infantile faces up to the sun, often made me pause and admire. It is prettier than the violet, and larger and deeper colored than our houstonia. It is a small and delicate edition of our hepatica, done in indigo blue and wonted to the grass in the fields and by the waysides. "The little speedwell's darling blue," sings Tennyson. I saw it blooming, with the daisy and the buttercup, upon the grave of Carlyle. The tender human and poetic element of this stern rocky nature was well expressed by it. In the Lake district I saw meadows purple with a species of wild geranium, probably _Geranium pratense_. It answered well to our wild geranium, which in May sometimes covers wettish meadows in the same manner, except that this English species was of a dark blue purple. Prunella, I noticed, was of a much deeper purple there than at home. The purple orchids also were stronger colored, but less graceful and pleasing, than our own. One species which I noticed in June, with habits similar to our purple fringed-orchis, perhaps the pyramidal orchis, had quite a coarse, plebeian look. Probably the most striking blue and purple wild flowers we have are of European origin, as succory, blue-weed or bugloss, vervain, purple loosestrife, and harebell. These colors, except with the fall asters and gentians, seem rather unstable in our flora. It has been observed by the Norwegian botanist Schübeler that plants and trees in the higher latitudes have larger leaves and larger flowers than farther south, and that many flowers which are white in the south become violet in the far north. This agrees with my own observation. The feebler light necessitates more leaf surface, and the fewer insects necessitate larger and more showy flowers to attract them and secure cross-fertilization. Blackberry blossoms, so white with us, are a decided pink in England. The same is true of the water-plantain. Our houstonia and hepatica would probably become a deep blue in that country. The marine climate probably has something to do also with this high color of the British flowers, as I have noticed that on our New England coast the same flowers are deeper tinted than they are in the interior.
