which might be as effective as the specified good commercial practice 
outlined in this bulletin (p. 3). Of the 449 machines at the 126 
factories inspected a dozen or more makes were found, no one being 
exceptionally prevalent. The relative distribution of the five makes 
most often found was 26, 15, 13, 12, and 11 per cent. The limited 
number of some makes can without doubt be attributed to the rela- 
tively short time they have been on the market. 
The claims made for some of these machines by the manufacturers, 
as taken from their literature, are summarized in Table 10. 
Few machines having a capacity in excess of 5 pounds are listed, 
indicating a predominant demand for the smaller sizes. Table 10 
shows also that nearly all manufacturers have different machines for 
packing different types of products, such as tea, cocoa, and rice.
