Rh On these accounts there should be variations from other indices as appears in the following comparisons:

Even with the above explanations there ought not to be such great differences as appear, especially among the several indices for commodity prices after 1916. There is fair agreement between my indices and those of the Bureau of Labor for the years except 1919-20. The discrepancies for those years are probably asso- ciated with the chaotic conditions of 1920. These comparisons throw doubt upon the commonly accepted indices of commodity prices.

Among the several indices for the physical volume of production there are not such great differences.
