Bring home with you the big brown silky cocoons of cecropia--the largest cocoon you will find, lashed all along its length to its twig, and usually near the ground. Look on the black cherry, the barberry, sassafras, and roadside and garden trees for the harder, whiter cocoon of the promethea moth. This hangs by its tip, because the caterpillar has begun his house by using the leaf, spinning it into the cocoon as part of its walls, much as does the wretched “brown-tail.” The gray cocoons, or rather nests, of this “brown-tail” moth you must bring home to burn, for they are one of our greatest pests. You will find them full of tiny caterpillars as you tear them open. Bring home your collection and, with the help of such a book as “Moths and Butterflies” by Mary C. Dickerson, identify them and hang them up for their “coming out” in the spring. V If you live in the city, you ought to go up frequently to your roof and watch for the birds that fly over. If in one of our many cities near the water, you will have a chance that those in the country seldom have, of seeing the seabirds--the white herring gulls (the young gulls are brown, and look like a different species), as they pass over whistling plaintively, and others of the wild seafowl, that merely to hear and see in the smoky air of the city, is almost as refreshing as an ocean voyage. Then there are the parks and public gardens--never without their birds and, at the fall migrating time, often sheltering the very rarest of visitors. VI In order to give point and purpose to one of these autumn outings, you should take your basket, or botanizing can, and scour the woods and fields for autumn berries. No bunch of flowers in June could be lovelier than the bunch of autumn berries that you can gather from thicket and wayside to carry home. And then, in order to enjoy the trip all over again, read James Buckham’s exquisite story, “A Quest for Fall Berries,” in his book, “Where Town and Country Meet.” VII Take your botany can on a trip toward the end of November and see how many blossoming flowers you can bring home from the woods. Wild flowers _after_ Thanksgiving in any northern state? Make the search, on all the southern slopes and in all the sheltered corners and see for yourselves. When you get back, you will want to read Mr. Bradford Torrey’s account of the flowers that he found blossoming out of doors in New England in the month of November. But who is Mr. Bradford Torrey? and where can you find this account of his November walk? You do not know? Well, then there is something more for you to do this fall. VIII
