The Black Oat, Avena sativa, has become a terrible weed in South Australia, which is singular, as the variety, the sterilis, its near relative, is a great blessing to California, over which it has been widely diffused. Schomburgh says, "The Black Oat has the most notorious preeminence of all the introduced weeds, and the effects of this intruder are the most ruinous to the farming community. Thousands of acres of arable land are totally ruined for the purposes of wheat growing by the Black Oat".

The United States Consul at Florence, Italy, gives, in a report to the State Department, an account of the flour made from chestnuts and used in many parts of Southern Europe. The writer says:

The number of trees in Tuscany and Lucca is estimated at several millions, and the nut and wood have done more to maintain the population of some of these districts than any other production. In some places wheat flour and corn meal are entirely superseded by the chestnut flour, which is very nourishing and much cheaper as an article of food.

Mr. Crosby is of opinion, after a careful study of the subject, that this variety of chestnut can be grafted on the native American species, and thus be made a source of wealth and profit in this country, especially in certain mountainous districts, where it is almost impossible to raise cereals, owing to the nature of the soil and the steepness of the mountain sides, and where transportation is so difficult and labor so high and scarce. Outside of this question of using the chestnut for food in the districts where it could be cultivated and grown to advantage in the United States, the present price of the imported Spanish chestnut, which is used for various purposes throughout our country, would, he claims, amply repay any outlay farmers might have to make in importing scions or shoots of this magnificent variety from Italy, for grafting on our own chestnut trees. * * * *

The flour can be preserved for two years. It is used in the same way as wheat flour, and though less nutritious, is much cheaper; and, at the same time, exceedingly agreeable to the taste. He says that, in those regions where the inhabitants live almost entirely on the chestnut, they are of better appearance and more healthy.

A lost ring is making newspaper paragraphs; the favorite story of Sir Walter Scott was about the same topic: A serving man was sent by his employer to a neighboring town to have a diamond ring mended; crossing a brook he dropped it into the stream, ran away to India and returning wealthy after twenty years, went with a friend to make restitution. Coming to the stream, "there" said he, "I lost that terrible ring "; as he spoke he placed his cane in the water, and on withdrawing it, behold the ring was on the ferule at the end of it!
