A recent development in the distribution of this compound has been 
local manufacture of nicotine dust. This involves both mixing and 
distribution by local dealers or growers and makes available high grade 
dust in small quantities. 
Nicotine dust prepared by a large manufacturer and shipped long 
distances is necessarily somewhat high-priced. To the cost of making 
and the manufacturer’s profit, must be added necessary profits for the 
distributor and retailer, which, with rather high freight rates, may 
make the price per pound almost double the actual cost of the raw 
materials. 
Mixing machinery is neither very expensive nor complicated. As a 
consequence, local dealers in communities where there is considerable 
demand for nicotine dust, especially where they are located at some 
distance from a manufacturer, are installing their own machinery, and 
buying the raw products, mixing and selling the dust directly to the 
growers. When this is done the distributor’s profit, and often the 
retailer’s profit can be deducted, as well as the freight charges, which 
permits the sale of the dust at a very low rate. 
The large manufacturer can, of course, compete with such local 
manufacturers by installing mixing machinery at his branch houses, 
and by dealing directly with retailers or growers, thus eliminating 
freight rates for long hauls on the manufactured dust, and also the 
distributor’s or jobber’s profit. It is probable that ultimately most of 
the nicotine dust will be made either in the self-mixing machines, or by 
a number of comparatively small local manufacturers, distributed over
