We have several calls for an explanation of the figures following the name of subscribers as printed upon this paper each week. The first two figures indicate the volume, and the last figure or figures the number of the last paper of that volume for which the subscriber has paid: EXAMPLE: John Smith, 56-26. John has paid for THE PRAIRIE FARMER to the first of July of the present year, volume 56. Any subscriber can at once tell when his subscription expires by referring to volume and number as given on first page of the paper. RENEW! RENEW!! Remember that every yearly subscriber, either new or renewing, sending us $2, receives a splendid new map of the United States and Canada--58x41 inches--FREE. Or, if preferred, one of the books offered in another column. It is not necessary to wait until a subscription expires before renewing.

This has been one of the most remarkable potatoes known in the history of this esculent. * * * * * A Gentleman residing at Milk's Grove, Iroquois county, Illinois has obtained a patent for a new and cheap building material; this material is straw and concrete pressed together and bound with wires. He thinks he has a good thing. Time will tell. * * * * * The Chamber of Commerce at Lyons, France, protests to the government against the embargo on American pork. Trichiniasis prevails in various parts of the German empire. It is traced to the use of uncooked home-grown pork. Here we score two points in favor of the American hog product. * * * * * The excellent articles on Silk Culture by E. L. Meyer, Esq., have attracted very general attention, as is proven by the number of letters we have received asking for his address. This was unintentionally omitted. Mr. Meyer resides at Hutchinson, Kan. The article was originally prepared for the quarterly report of the Kansas Board of Agriculture. * * * * *
