Chemical Section. 
In 1888 and 1889, there was undertaken by 
this Section cf the Experiment Station, a study of the 
tobaccos grown by the Section of Horticulture. This was 
to comprise an analysis of the ash of each variety, for 
purposes of comparison; and, also, analyses of the same 
variety when grown upon rich (fertilized) soil and poor 
(unfertilized) soil. 
Before giving the results of such work, a few words 
as to the work heretofore performed, and results attained, 
may not be out of place, as showing how this crop is 
affected by various circumstances. 
In general, it has been found that the plant varies in 
texture and quality with the climate, the soil, the fertilizer 
used, and, perhaps, from other circumstances attending its 
growth and cultivation. 
CLIMATE. 
The climate has more influence on the quality of 
tobacco than soil or manner of cultivation. The proper 
degree of heat, of moisture, and the influence of sunlight 
have much to do with the development of the aromatic 
principle for which certain brands of tobacco are so 
highly esteemed. Colorado has excellent conditions for 
producing tobacco of fine quality. The summer climate is 
superb, giving that heat and dryness so essential, and with
