A short note from Popular Science Monthly in which Prof. Riley of St. Louis corrects an earlier calculation about the mulberry silk-worm's cocoon. He states that the thread averages little more than half a mile and seldom exceeds 1,000 yards, rather than the 11 miles previously claimed. He also gives the weight of a mile of thread as about 15½ grains.
