The weather stations are distinguished under a classification made by a special service performed at each, and are known as telegraph, printing, display, special river, cotton region, and sunset stations. A number of them may have all the special features indicated by the different names, while others may have but the one feature which gives it its place in the class. The last mentioned are so called, not, as the name may possibly suggest, because they are located away off toward sundown, but because of the special observation taken at the time of sunset which affords so good an indication of the probable weather for to-morrow. It recalls the fact that the Jews were reminded more than eighteen hundred years ago of their habit of observation in this particular, which was a rebuke for their failure to read “the signs of the times.” A great number of reports are received at the Weather Bureau weekly and monthly, by mail from volunteer observers, from medical officers at military posts, from agricultural and scientific societies, and at regular times from meteorological societies in the old world, but as none but the telegraphic reports have more than a relative connection with the work of weather indications for which we are looking day after day, it is sufficient for the purposes of this article to simply mention the fact that there are several hundred of these mail reports from which record of permanent and daily increasing value is made for study and information of the climate in various sections of the country.
