 in addition to the zinc recorded in the foregoing data on physical inventories
at plants, several thousand tons were in transit and held for redistillation
at the end of each month The total of this additional metal ranged from as
low as 10,530 tons to as high as 15,924 tons for month-ends from December
3 1, 1940, to t~ccem bei 31, 1941, with an average of about 13,200 tons a
month for the year.
 Although the monthly stock data do give a general picture, the~ resu.lts
for July through December are not directly comparable with preceding months,
because of variance in coverage and certain changes in industrial classification.
These differences are indicated by the following table, which gives the final
stock totals for the beginning and end of 1941, based upon an annual consunier
surveyfor the calendar year 1941. Total inventories decreased 11 percent.
