There are many good books on the use of the camera for nature-study. Among them read: “Nature and the Camera” by Dugmore; “Home Life of Wild Birds,” by Herrick. PAGE 4 _The clover blossom and the bumblebee_: Read the intensely interesting book of Darwin’s on the cross-fertilization of flowers. You will also find readable accounts in “Nature’s Garden,” by Mrs. Blanchan. PAGE 5 In what nursery book do you find the original account of _the House that Jack Built_? PAGE 6 _Coccinella septempunctata_: The ladybirds, or ladybugs, are named according to the number of their spots: _septempunctata_ means seven-spotted. Another is called _novemnotata_, nine-spotted. _Sixty species of birds_: Make your own list. Study your woods, your neighborhood, minutely day and night in order to find them all. CHAPTER II TO THE TEACHER Set the students to watching and reporting this rare but very interesting phase of wild animal life. Nothing will tax their patience and ingenuity more; nor will any of their reports need so careful scrutiny and weighing, so easy is it to be mistaken. FOR THE PUPIL PAGE 10 _“line”_: the end of the race; the “tape” or mark set for runners in a contest. _“set-to”_: a combat or fight. _mix-up_: is the same half-slangy word or newspaper expression for a general fight. PAGE 11 _Paramœcium_: this is one of the best known of the single-celled animals. You can get them by making an “infusion” of raw potato, a little hay, and stagnant water. PAGE 12 _A writer in one of our magazines_: The account is found in “St. Nicholas” for May, 1913. _two big slanting cellar-doors_: These were in the shed of my grandfather’s farmhouse, “Underwood,” and covered the “bulkhead” of the cellar. PAGE 13 _The [Massachusetts] Society for the Prevention of Cruelty to Animals_: has its headquarters in Boston. It does a great work for “dumb” animals, and publishes a paper called “Our Dumb Animals” that every home and school should have. PAGE 14 _follow my leader_: a game that all boys know and love, especially when a strong, daring leader takes the game in hand. PAGE 15 _Mount Hood_: is the highest peak of the Cascade Range in Oregon. The _rope_ hanging down from the summit was brought up on a pack-horse or mule (I forget which) as far as Tie-up Rock, then carried to the summit by the professional guides and there fastened for the safety of those whom they take to the top during the summer. PAGE 17 _a wild snowstorm_: for a fuller description of this storm and the whole climb see the chapter in “Where Rolls the Oregon” entitled “The Butterflies of Mount Hood.” CHAPTER III FOR THE PUPIL PAGE 19 _"All heaven and earth are still,” etc._: this is from Byron’s “Childe Harold’s Pilgrimage,” a poem you ought to read.
