familiar.

To the man or woman who is somewhat at home in the plant-world, travel is quite a different thing from what it is to one who does not know a mint from a mustard. The shortest journey to a new locality is full of interest to the traveller who is striving to lengthen his list of plant acquaintances. The tedious waits around the railway station are welcomed as opportunities for fresh discoveries. The slow local train receives blessings instead of anathemas because of the superiority of its windows as posts of observation. The long stage ride is too short to satisfy the plant-lover who is keeping count of the different species by the roadside.

While crossing the continent on the Canadian Pacific Railway a few years ago, the days spent in traversing the vast plains east of the Rockies were days of keen enjoyment on account of the new plants seen from my window and gathered breathlessly for identification during the brief stops. But to most of my fellow-passengers they were days of unmitigated boredom. They could not comprehend the reluctance with which I met each nightfall as an interruption to my watch.

When, finally, one cold June morning we climbed the glorious Canadian Rockies and were driven to the hotel at Banff, where we were to rest for twenty-four hours, the enjoyment of the previous week was crowned by seeing the dining-room tables decorated with a flower which I had never succeeded in finding in the woods at home. It was the lovely little orchid, Calypso borealis, a shy, wild creature which had been brought to me from the mountains of Vermont. It seemed almost desecration to force this little aristocrat to consort with the pepper-pots and pickles of a hotel dining-room. In my eagerness to see Calypso in her forest-home I could scarcely wait to eat the breakfast for which a few moments before I had been painfully hungry.

Unfortunately the waiters at Banff were proved as ruthless as vandals in other parts of the world. Among the pines that clothed the lower mountain-sides I found many plants of Calypso, but only one or two of the delicate blossoms had been left to gladden the eyes of those who love to see a flower in the wild beauty of its natural surroundings.

That same eventful day had in store for me another delight as the result of my love for plants. For a long time I had wished to know the shooting-star, a flower with whose general appearance from pictures or from descriptions I was familiar. I knew that it grew in this part of the world, but during a careful search of the woods and meadows and of the banks of the rushing streams the only shooting-star I discovered was a faded blossom which someone had picked and flung upon the mountain-path. Late in the afternoon, having given up the hope of any fresh find, I went for a swim in the warm sulphur pool. While paddling about the clear water, revelling in the beauty of the surroundings and the sheer physical joy of the moment, my eyes fell suddenly on a cluster of pink, cyclamen-like blossoms springing from the opposite rocks. I recognized at once the pretty shooting-star.

Two days later, at Glacier, I had another pleasure from the same source in the discovery of great beds of nodding golden lilies, the western species of adder's tongue, growing close to white fields of snow.

The enjoyment of the entire trip to the Pacific coast, of the voyage among the islands and glaciers of Alaska, and of the journey home through the Yellowstone and across our Western prairies, was increased indescribably by the new plants I learned to know.

The pleasure we take in literature, as in travel, is enhanced by a knowledge of nature. Not only are we able better to appreciate writers on nature so original and inspiring as Thoreau, or so charming as John Burroughs, but such nature-loving poets as Wordsworth, Lowell, Bryant, and countless others, mean infinitely more to the man or woman who with a love of poetry combines a knowledge of the plants and birds mentioned in the poems.

Books of travel are usually far more interesting if we have some knowledge of botany and zoölogy. This is also true of biographies which deal with men or women who find either their work or their recreation—and how many men and women who have been powers for good may be counted in one class or the other—in some department of natural science.

One fascinating department of nature-study, that of ferns, has received but little attention in this country. Within the last few years we have been supplied with excellent and inexpensive hand-books to our birds, butterflies, trees, and flowers. But so far as I know, with the exception of Mr. Williamson's little volume on the "Ferns of Kentucky," we have no book with sufficient text and illustrations within the reach of the brains and purse of the average fern-lover. In England one finds books of all sizes and prices on the English ferns, while our beautiful American ferns are almost unknown, owing probably to the lack of attractive and inexpensive fern literature. Eaton's finely illustrated work on the "Ferns of North America" is entirely out of the question on account of its expense; and the "Illustrated Flora" of Britton & Brown is also beyond the reach of the ordinary plant-lover. Miss Price's "Fern Collectors' Hand-book" is helpful, but it is without descriptive text. "Our Native Ferns and their Allies," by Mr. Underwood, is exhaustive and authoritative, but it is extremely technical and the different species are not illustrated. Mr. Dodge's pamphlet on the "Ferns and Fern Allies of New England" is excellent so far as it goes, the descriptions not being so technical as to confuse the beginner. But this also is not illustrated, while Mr. Knobel's pamphlet, "The Ferns and Evergreens of New England," has clear black-and-white illustrations of many species, but it has no text of importance.

In view of the singular grace and charm of the fern tribe, patent to the most careless observer, this lack of fern literature is surprising. It is possible that Thoreau is right in claiming that "we all feel the ferns to be farther from us essentially and sympathetically than the phenogamous plants, the roses and weeds for instance." This may be true in spite of the fact that to some of us the charm of ferns is as great, their beauty more subtle, than that of the flowering plants, and to learn to know them by name, to trace them to their homes, and to observe their habits is attended with an interest as keen, perhaps keener, than that which attends the study of the names, haunts, and habits of the flowers.

That ferns possess a peculiar power of blinding their votaries to the actual position they occupy in the minds of people in general seems to me evidenced by the following quotations, taken respectively from Mr. Underwood's and Mr. Williamson's introductions.

So competent and coldly scientific an authority as Mr. Underwood opens his book with these words:
