PREFACE Mushrooms and their extensive and profitable culture should concern every one. For home consumption they are a healthful and grateful food, and for market, when successfully grown, they become a most profitable crop. We can have in America the best market in the world for fresh mushrooms; the demand for them is increasing, and the supply has always been inadequate. The price for them here is... more...

The subject of inheritance is an immense one, and has been treated by many authors. One work alone, 'De l'Hérédité Naturelle,' by Dr. Prosper Lucas, runs to the length of 1562 pages. We must confine ourselves to certain points which have an important bearing on the general subject of variation, both with domestic and natural productions. It is obvious that a variation which is not... more...

CHIRP THE FIRST. The winter of 1878 was certainly an unusually dreary one, and so thought a remarkably fine young Blackbird, as he perched one morning on the bare bough of a spreading lime-tree, whose last brown leaf had fallen to the ground some weeks before. With the exception of the Scotch firs and other fortunate evergreens, there was nothing to be seen on all sides but leafless branches standing... more...

The Swan. The Swan is a very beautiful bird. It is generally white, though a black swan has been discovered in Australia. It is not very often seen in this country. It was brought from Asia and Eastern Europe into England—from whence, most probably, a few specimens have been introduced into this country. The Swan is very graceful in the water, but on land it is an awkward waddler. The Coot is... more...

CHAPTER XII. THE MULBERRY FAMILY. "There is a fruit tree," said Miss Harson, "belonging to an entirely different family, which we have not considered yet; and, although it is not a common tree with us, one specimen of it is to be found in Mrs. Bush's garden, where you have all enjoyed the fruit very much. What is it?" "Mulberry," said Clara, promptly, while Malcolm was... more...

IMPORTANCE OF RODENT GROUPS. As the serious character of the depredations by harmful rodents is recognized, State, Federal, and private expenditures for their control increase year by year. These depredations include not only the attacks by introduced rats and mice on food materials stored in granaries, warehouses, commercial establishments, docks, and private houses, but also, particularly in the... more...

CHAPTER I. PHYSICAL GEOGRAPHY. From a look at a globe or a map of the Eastern hemisphere, we shall perceive between Asia and Australia a number of large and small islands forming a connected group distinct from those great masses of land, and having little connection with either of them. Situated upon the Equator, and bathed by the tepid water of the great tropical oceans, this region enjoys a climate... more...

LET us now, in order to form a clearer conception of the bees' intellectual power, proceed to consider their methods of inter-communication. There can be no doubting that they understand each other; and indeed it were surely impossible for a republic so considerable, wherein the labours are so varied and so marvellously combined, to subsist amid the silence and spiritual isolation of so many... more...

MY ROBIN There came to me among the letters I received last spring one which touched me very closely. It was a letter full of delightful things but the delightful thing which so reached my soul was a question. The writer had been reading "The Secret Garden" and her question was this: "Did you own the original of the robin? He could not have been a mere creature of fantasy. I feel sure you... more...

CHAPTER I PARASITISM AND DISEASE PARASITES he dictionary says that a parasite is a living organism, either animal or plant, that lives in or on some other organism from which it derives its nourishment for a whole or part of its existence. This definition will serve as well as any, as it seems to include all the forms that might be classed as parasites. As a general thing, however, we are accustomed to... more...
