 Production of oyster-shell products, 1921 to 1930 



FRESH-WATER MUSSEL-SHELL PRODUCTS 



In 1930 products manufactured from fresh-water mussel shells 

 were valued at $5,007,419, which is a decrease of 19 per cent as com- 

 pared with the value of the production in 1929. Of the total produc- 

 tion, 96 per cent of the value consisted of pearl buttons. The remain- 

 ing products included crushed shell for poultry feed, lime, cut shells, 

 stucco, colored and natural color shells, and shell chips used for 

 decorative purposes and "pearl novelties." The total production of 

 finished pearl buttons from fresh-water mussel shells amounted to 

 15,433,944 gross, valued at $4,785,881. The products from the 

 fresh-water mussel-shell industry which were manufactured in Iowa 

 accounted for 71 per cent of the total. 



Mussel shells utilized in the above production amounted to 

 59,490,000 pounds, valued at $1,092,156. Shells were taken in 17 

 States in the Mississippi Valley and Great Lakes region. The 

 larger producing States were Arkansas, with 31 per cent of the total 

 shells; Illinois, 14 per cent; Tennessee, 13 per cent; Indiana, 9 per 

 cent; Michigan, 8 per cent; and Iowa, 6 per cent.
