The numberless uses for india-rubber in this century has made it an indispensable article of commerce and manufacture, consequently its production has become a great industry. Whether the known forests will continue to supply the demand for any considerable time is a practical question. Right here comes the intelligence, that the attention of the government in India has been called to a new source of this useful gum. This new plant which yields large quantities of pure caoutchouc is a native of Cochin China, and is common in Southern India. It belongs to the _dog-bane_ family (the same family that yields strychnine), and is called _Prameria Glandalifera_. In lower China its liquid juice is used for medicine by the Anamites and Cambodians, and it also appears among the drugs of China. * * * * * The Norwegian, Schübeler, mentions some striking peculiarities of plants in high latitudes. He says that seeds produced in these regions are much larger and weigh more than those grown in more temperate climates. The leaves, also, of most plants are larger in the north than those of the same species farther south. Flowers which are white in warmer climates, become colored when they blossom in the north. All these differences he ascribes to the continued light of long days. * * * * * It is noted by naturalists that Arctic plants are destitute of odor as a rule; only a few having a faint scent. * * * * * It appears from an English paper that the secretary of the Royal Society transplanted sea-weed to earth that was kept constantly moist, and that the plants grew and flourished under what would seem to be very unnatural circumstances. This would be an experiment worth trying with our fresh water plants. * * * * * By placing the stems of freshly cut flowers in a liquid dye their petals may often be colored or changed in color. This will not always happen, however, as certain colors are not absorbed by flowers. These dyes do not in any way change or affect the perfume or freshness. * * * * *
