Lo! now the labour of Hercules when he set about bringing up Cerberus from below, and all the work done by Apollo in the years when he ground corn, are but a little matter compared with the attempt to master botany. Great minds have been at it these two thousand years, and yet we are still only nibbling at the edge of the leaf, as the ploughboys bite the young hawthorn in spring. The mere classification--all plant-lore was a vast chaos till there came the man of Sweden, the great Linnaeus, till the sexes were recognised, and everything was ruled out and set in place again. A wonderful man! I think it would be true to say it was Linnaeus who set the world on its present twist of thinking, and levered our mental globe a little more perpendicular to the ecliptic. He actually gathered the dandelion and took it to bits like a scientific child; he touched nature with his fingers instead of sitting looking out of window--perhaps the first man who had ever done so for seventeen hundred years or so, since superstition blighted the progress of pagan Rome. The work he did! But no one reads Linnaeus now; the folios, indeed, might moulder to dust without loss, because his spirit has got into the minds of men, and the text is of little consequence. The best book he wrote to read now is the delightful 'Tour in Lapland,' with its quaint pen-and-ink sketches, so realistically vivid, as if the thing sketched had been banged on the paper and so left its impress. I have read it three times, and I still cherish the old yellow pages; it is the best botanical book, written by the greatest of botanists, specially sent on a botanical expedition, and it contains nothing about botany. It tells you about the canoes, and the hard cheese, and the Laplander's warehouse on top of a pole, like a pigeon-house; and the innocent way in which the maiden helped the traveller in his bath, and how the aged men ran so fast that the devil could not catch them; and, best of all, because it gives a smack in the face to modern pseudo-scientific medical cant about hygiene, showing how the Laplanders break every 'law,' human and 'divine', ventilation, bath, and diet--all the trash--and therefore enjoy the most excellent health, and live to a great old age. Still I have not succeeded in describing the immense labour there was in learning to distinguish plants on the Linnaean system. Then comes in order of time the natural system, the geographical distribution; then there is the geological relationship, so to say, to Pliocene plants, natural selection and evolution. Of that let us say nothing; let sleeping dogs lie, and evolution is a very weary dog. Most charming, however, will be found the later studies of naturalists on the interdependence of flowers and insects; there is another work the dandelion has got to do--endless, endless botany! Where did the plants come from at first? Did they come creeping up out of the sea at the edge of the estuaries, and gradually
