In April, 1879, the corporation of the city of London were asked to co-operate in this work, and to undertake the erection of suitable memorial tablets within the city boundaries. The matter was referred to the city lands committee, with which body the secretary has had several communications with respect to the localities suggested for memorials, the result being that the committee agreed to erect such tablets within the city boundaries.--_Journal of the Society of Arts._ * * * * * DOMESTIC SUGAR PRODUCTION. The value of sugar imported into the United States, is greater than that of any other single article of commerce. In the year 1880 it appears that over one thousand eight hundred and twenty-nine million pounds of sugar were brought here from other countries, at a cost of nearly one hundred and twenty million dollars, including customs duty. Moreover, the consumption of sugar, _per capita_, in this country is rapidly increasing. It was, during the ten years next preceding 1870, only 28 pounds on the average per annum, but, in the ten years next following, an average of 38 pounds per annum were consumed for each person of the population of this country. This appears to be an increase of 35 per centum in ten years. The subject of domestic cultivation of sugar bearing plants is, therefore, one of great importance to this nation, and it has accordingly engaged the attention of the U.S. Commissioner of Agriculture, and many experiments have been made in different parts of the country in the propagation of the various canes, roots, etc., from which sugar can be made. Among sugar-bearing plants, beside the regular sugar cane, are, sorghum, sugar beet, maple, watermelon, sweet and white potato, and corn stalk. Statistics show that of the 12,000,000,000 pounds of sugar produced in the world, about three-fourths comes from the sugar cane, and the other fourth comes mainly from the sugar beet. Of the total quantity, only about one seventieth is produced in the United States, and that is mainly cane sugar from Louisiana. The beet sugar has formerly been mainly produced in Europe. First France, second Germany, third Russia, then Belgium, Austria, Holland, Sweden, and Italy. The consumption of sugar in Great Britain is much greater _per capita_ than in the United States, about 65 pounds, or nearly double; while in Germany 19 pounds per annum are used on an average by each person, and in Russia the consumption is much less.
