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.* 



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 win- 

 ter 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.
