A variety came later to this country from Africa, through the agency of an Englishman named Wray, to whom is charged the effects of the delusive experiments of trying to make crystallized sugar from its juice, which have been going on in this country for twenty years. But two varieties of sorghum now remain, known as the Chinese and African types. Of all the other sugar plants, none except the maple tree (besides the sugar cane and the beet) seem to have yielded sugar to pay the cost of manufacture. The maple tree has yielded a total of 41,000,000 pounds in 1877. But as an industry by itself, it appears to be unprofitable, and maple sugar must be, and generally is, sold at a higher price per pound than cane sugar; moreover, it has not the qualities that are required in a general sweetner for culinary purposes. The variety of sugar plant called amber cane is not very clearly defined, but it may be taken, from the description of the juice as to crystallizing qualities, as no better sugar producer than sorghum. It, with sorghum, is classed as a sub-variety of sugar cane, which will yield sirup and fodder, but will not crystallize under several months' time, and even then in but small percentage. On the whole it appears, as before stated, that the sugar beet is the only practicable source of sugar for the Northern States, which, as experimentally shown, can be raised at a profit of forty six dollars per acre, against twenty dollars per acre, the profit of sugar making from cane in Louisiana. Upon this showing several beet sugar factories have been started in the United States and in Canada, and their products are said to be satisfactory, and have been sold at a profit in competition with imported beet sugar. Mr. Ware recommends the establishment of beet sugar factories on a larger scale, to be managed by men who have had experience in this particular kind of sugar making, which seems to be a practical means of supplying ourselves with home-made sugar. It must be remembered, however, that the successful cultivation of an ample supply of beets to keep them at work is an essential prerequisite. * * * * * HERALD ISLAND. John Muir, the geologist with the Corwin Arctic Expedition, describes, as follows, the characteristics of Herald Island, hitherto known only as an inaccessible rock seen by a few venturesome whalers and explorers:
