MISCELLANEOUS NOTES.

RUBBER trees are reported found growing in Manatee County, Fla.

JAPAN proposes to build up her commercial navy by giving

subsidies to ship builders on every ton above 1,000, and to ship

owners for ships of 1,000 tons that can make ten knots an hour, the

subsidy being increased for every 500 tons additional burden or every

knot additional speed.

ROSA BONHEUR began to work seriously at painting when she was

about fifteen, and donned male attire so that she could go about

without attracting attention. She wore it so naturally that no one

ever suspected her of being a girl, and found it so comfortable that

she has worn it ever since to work in. She and Mme. Dieulafoy, the

wife of the explorer, are the only two women in France who are legally

authorized to appear in public in men's clothes.

A DEVICE for permitting the unsophisticated guest to blow out

the gas in his bedroom at the city hotel without inconvenience to

himself or anybody else has been devised. The gas burner is made of a

metal having great expansive and contractive properties. The gas is

turned on in the regular way and a small screw is turned which admits

a small flow of gas through the burner. The gas is lighted, and the

heat expands the metal and automatically opens a valve permitting a

full flow of gas. The gas can be turned off in the ordinary way, but

if the gas is blown out the metal contracts, closing the valve, and

all the gas that escapes is the very small quantity admitted by the

screw valve.

A MOVEMENT is on foot in Europe having for its object the

securing of a complete census of the inhabitants of all the civilized

countries of the world. With this end in view the several governments

are to be approached with the request that they will endeavor to

decide upon a mutual date for counting the people under their various

jurisdictions. Heretofore the different countries have taken their

census on different dates, and it has been impossible to obtain

accurate statistics in regard to the world's population at any one

particular period. It is suggested that the last year of the present

century or the first year of the coming century would be the most

appropriate date for obtaining statistics.

OF THE 376 suicides who ended their lives in New York last

year, by far the greater number were divorced people, says the Medical

Review. From a table prepared for the year 1895, it is shown that

there were in Germany during that year 2,834 suicides of men either

divorced or separated from their wives and 948 suicides of widowers,

as against only 286 suicides of married men. It is also shown that 343

women separated from their husbands and 124 widows died by their own

hands, in contrast with 61 married women and 87 unmarried. In

Wurtemburg, to every million inhabitants, there are 1,540 lunatics

among divorcés or women separated from their husbands and 338 among

the widows, while there are only 224 among unmarried women. There are

1,484 lunatics among the men who are divorced or separated from their

wives, 338 among the widowers, and only 236 among the bachelors.

THE QUARTERLY list of American tin plate works, which was

published in the Metal Worker a short time ago, shows that on July 1

there were thirty-six complete tin plate plants rolling their own

black plates in actual operation in the United States and three in

course of construction. The active plants possessed an aggregate of

179 tin mills, having an estimated yearly capacity of about 5,500,000

boxes of tin plates. In addition to these establishments there were

thirty-one tin plate dipping works, without rolling mills, possessing

an aggregate of 169 tinning sets. At the end of June the production of

American tin plate is estimated to have been going on at the rate of

over 4,000,000 boxes yearly. During the last quarter the New Castle

Steel and Tin Plate Company, of New Castle, Pa., has completed large

extensions to its works, making it an eighteen-mill plant. This gives

the United States the largest and most complete tin plate works in the

world. Its annual capacity is three-quarters of a million boxes.

THE MONITEUR VINICOLE has recently published a statement

showing the wine production of the various countries of the world.

From this statement it appears the yield in France amounted in the

years 1895 and 1894 to 587,127,000 gallons and 859,162,000 gallons

respectively; in Algeria to 83,549,000 and 80,124,000 gallons; Tunis,

3,956,000 and 3,936,000: Italy, 469,555,000 and 539,000,000; Spain

379,500,000 and 528,000,000; Portugal, 43,890,000 and 33,000,000;

Azores, Canaries, and Madeira, 4,620,000 and 2,640,000; Austria,

66,000,000 and 88,000,000; Hungary, 63,030,000 and 46,103,000; and

Germany, 80,190,000 and 110,000,000 gallons. In Turkey and Cyprus the

production last year amounted to 52,800,000 gallons, and this compares

with an average yield of 40,000,000 gallons. In Bulgaria the yield was

26,400,000 gallons; Servia, 17,600,000; Greece, 35,200,000; Roumania,

68,640,000; Switzerland, 27,500,000; the United States, 89,700,000;

Mexico, 1,980,000; Argentine Republic, 29,700,000; Chile, 33,000,000,

Brazil, 7,700,000; Cape of Good Hope, 2,420,000; Persia, 594,000; and

Australia, 3,300,000 gallons.

THE Historical Museum of Hesse Cassel, in Germany, says the

Carpenter and Builder, contains a most remarkable collection of

curiosities. It is in the form of a wooden library, composed of five

hundred and forty volumes of folio and quarto sizes. The books are

made of the different specimens of trees found in the famous park of

Wilhelmshoehe. On the back of each of these singular books is pasted a

large shield of red morocco, which bears the popular and scientific

names of the tree and the family to which it belongs. Each label is

inlaid with some of the bark of the tree, the moss and lichen, and a

drop or two of the resin, if the tree produces it. The upper edge of

the book shows the tree in its youth, cut from a horizontal section,

with the sap in the center and the eccentric circles. The same method

prevails with the lower edge, showing the changes that have taken

place. The interior of the book, in the shape of a box, contains in

manuscript the history of the tree, with numerous hints as to its

treatment, capsules filled with seeds, buds, roots, leaves, and so on.

The inner sides show the diverse transformations which take place from

bloom to fruit.
