Excerpt from The Red Spider of Citrus Trees This sulfid of potash is of very little value, at least at this strength, as an insecticide, but is effective enough against the active stages of the mite. In order to kill the eggs and moulting forms it Will be necessary to make three applications, separated by intervals of one week. This will make a very clean sweep.

Book Description
Excerpt from The Red Spider on Cotton The minute reddish mite commonly known as the red spider appar ently is becoming one of the serious enemies of the cotton plant in the United States. It is now prevalent throughout the cotton belt, and, especially in the last few seasons, has caused much alarm among the farmers in certain sections. Seasons of excessive drought are favorable to the development Of the mite, and at such times the pest increases SO rapidly that the damage Often becomes severe before its presence is detected. Red-spider infestation is frequently miscalled rust by farmers, since infested leaves soon turn deep red on their upper surface. Sneh leaves, however, if examined underneath, reveal the presence Of the red spiders and the inconspicuous webs behind which they are feed ing and laying their eggs.

Excerpt from Red Spider We must not ask your father to watch again, ' said Hillary, with the corners of his mouth twitching. We believe what he says now when he tells us he is very shortsighted. I will come to-night and the night after, if need be, till I earn my guinea. The rascal has been here twice and has escaped. He shall not succeed the third time.

Book Description
Excerpt from Red Spider: A Novel Fifty years ago! Half a century has passed since the writer was a child in the parish where he has laid the scene of this tale. There he had a trusty nurse, and a somewhat romantic story was attached to her life. Faithful, good creature! She was carrying the writer in her arms over a brook by a bridge elevated high above the water, when the plank broke. She at once held up her charge over her head, with both arms, and made no attempt to save herself, thinking only of him, as she fell on the stones and into the water. He escaped wholly unhurt, owing to her devotion. Many years after, the author read a little German story which curiously recalled to him his nurse and her career. When a few years ago he revisited the scenes of his child hood, he thought to recall on paper many and many a recollection of village life in the south-west of England in one of its most still and forgotten corners. So he has taken this thread of story, not wholly original in its initiation, and has altered and twisted it to suit his purpose, and has strung on it sundry pictures of what was beginning to fade half a century ago in Devon. Old customs, modes of thought, of speech, quaint sayings, weird superstitions are all disappearing out of the country, utterly and for ever.
