who has published one of the fairest and most intelligent articles ever written on our climate, criticises the statistics so far published as inadequate, inasmuch as two of the three observations, on which they are based, occur at 5 a. m. and 9 p. m.—hours that in no way concern the invalid.[1] With a view to answering these objections and those of other writers, we append the following tables, compiled from the official data on record at the Signal-station in Denver. We have taken the months that may fairly be considered as the invalid's winter, and the hours that constitute the invalid's day, and we have selected the winter closest at hand (at the time of writing), so that the reader may from his recollection compare the data we present with the conditions existing at the place where he was at that time.
We furthermore hope that these figures may be of service to those who may be meditating coming to Colorado, as showing them what climatic conditions they may reasonably expect to find:

Fogs.—A study of these tables shows that such a thing as a fog is of very rare occurrence, there not being a single one recorded at any of the three observations.
