The blue prints of leaves and of flowers do not show anything but the outlines, of course. Leaf prints of other kinds are made which bring out the veining as well. The outfit for this work is simple. Two print rollers, a pane of glass, and a tube of printers' ink, sheets of paper to print upon, and leaves. Put a small quantity of the ink on the clean glass, and work it into a thin film over the surface. Lay a leaf upon this film of ink and go over it with the inky roller. Transfer the leaf to a sheet of paper and cover with a second sheet. One whirl of the clean roller ought to give you the desired print. It is surprising how delicate and true these are and how perfectly they show the characteristic margin, indentations, venation, and even something of the texture of each leaf. A little practice makes one able to make impressions which are like leaf shadows, so delicate and lace-like can these prints be made. It is an excellent way of fixing the leaf forms in the memory, as well as in the note-book. In making a collection of plants the same "rules of the game" should hold good as in collecting insects and other natural objects. Take only what you need. Do not uproot and leave to die the near neighbours of the specimens you select. The taking of rare specimens is discouraged. I shall never forget the look of indignation our dear old professor gave an ambitious youth who had uprooted for his paltry collection every plant of a species of rare fern which the professor had been trying for years to re-establish in its old location. After all is said and done, a live plant is better than a dead one. This is all a part of the great spirit of conservation that has so taken possession of our people of late years. Out of these little acts of preserving our resources will grow a more beautiful America and a better appreciation of all things beautiful. COLLECTING SEA-WEEDS Every child ought to be familiar with that musical poem of Percival's beginning: "Deep in the sea is a coral grove, Where the purple mullet and goldfish rove." And then when the child grows bigger he should have an opportunity to go out in a glass-bottomed boat, at Santa Catalina Island or elsewhere, and see for himself that those "yellow and scarlet tufts of ocean," "bending like corn on the upland lea," are not pictures from a poet's dream, but beautiful realities.
