A PRELIMINARY NOTICE. BY THOMAS H. MACBRIDE. The species listed here were collected during the month of August, 1897,' and represent the rather hasty gathering of a traveler who could not remain long enough at one place to do thorough work. The number of species ought to be extended to three times that here offered, and probably will be ere many seasons pass. The Black Hills exhibit a very considerable range of summer climate, remarkable when we consider the very restricted limits within which such variation is displayed, a region about equal to a dozen Iowa counties. The foot-hills and southern plateaus are in summer excessively dry, drouth-stricken. The occa- sional showers that pass seem to make no special impression, the water falling at such times being almost immediately evap- orated. On the other hand the central mountain peaks are covered with varied, flourishing, and abundant vegetation all summer long, seem to enjoy sufficient rainfall and are often enveloped by mists for days together, and are undisturbed by any hot, dry winds, from the southern and eastern plains such as constantly sweep and vex the lower levels. The temperature varies much also in different localities. At the lower levels, 1,000-2,000 feet, the heat by day is great, reaching 95-98° Fahr- enheit; on the higher levels, probably owing in part to more abundant moisture, the temperature of the air by day seldom rises above 70°, and is often much below. It is so cold in the central hills that corn does not mature, and even oats and bar ley during the short season fail betimes for the same
