We are very glad to see the interest which our readers have taken in the subject of "School-luncheons." Many boys and girls have sent in letters, thanking us for the article in our September number, and filled with sage bits of experience. We should like to acknowledge these separately, and print some of them, but can do no more here than express our thanks to our young correspondents, one and all, for their kind and hearty words. It will interest them all to know, however, that the article has attracted attention, and aroused enthusiasm among the older people too,--their fathers and mothers, and teachers, and even their favorite writers. For here, among the many letters it has brought us, is one that is peculiarly welcome. Our readers will have little difficulty in guessing who the writer is: August 26th. DEAR LITTLE SCHOOLMA'AM: Being much interested, as well as amused, by the luncheon article in ST. NICHOLAS for September, I should like to add one more to the list of odd luncheons. A pretty little dish of boiled rice, with a cake of molasses, or preserve of some sort, in the middle. This, fitted into a basket, and covered with a plate, goes safely, and, with the addition of a napkin and two spoons, makes a simple meal for hungry children. It may find favor in the eyes, or rather mouths, of the young readers of ST. NICHOLAS, not only because it is good, but because it was the favorite lunch once upon a time of two little girls who are now pretty well known as "Meg and Jo March." It may be well to add that these young persons never had dyspepsia in their lives,--pie and pickles, cake and candy being unknown "goodies" to them. With best wishes for the success of this much-needed reform in school-children's diet, I am, yours truly, L.M.A. * * * * * THE MOONS OF MARS. Since Professor Proctor wrote the paper entitled "Mars, the Planet of War," published in this number, there has been made, in relation to its subject, a discovery that the scientists say will rank among the most brilliant achievements of astronomy. A great difference once thought to exist between Mars and the other planets was that he had no moons; but during the night of the 16th of August, Professor Hall, of the U.S. Naval Observatory at Washington, D.C., actually saw through his telescope that Mars has a moon. On the 18th of August another was seen, smaller than the first and nearer to the planet. The larger satellite is believed to be not more than ten miles in diameter: it is less than 12,000 miles distant from its primary, and its period of revolution about it is 30 hours 14 minutes. The distance of the smaller moon is 3,300 miles, and its period 7 hours 38 minutes. There is no doubt that these newly found celestial bodies are the smallest known.
