A PRETTY LARGE CIRCLE.—A friend, writing to us about Uncle Tom's Cabin, says:

  "There have been twenty-five readers of my paper since the beginning of Mrs. Stowe's story. That number goes a little higher than the one you mentioned a few weeks ago."

  This is too hard usage for one newspaper. Five readers are as many as we can allow to a paper. We hope our friend will insist that every five at least of his circle of twenty-five shall take one copy of the Era.
