These figures show changes from year to year; in 1900 there was 

 an exceptional increase, both Spring and Fall, in such deficiencies; 

 but, this Spring, the number has dropped ba£k to normal. In most 

 samples which are found below guaranty at one point, there is an 

 excess at some other point, indicating that the cause of departure 

 from the composition guaranteed lay not in the failure of the manu- 

 facturer to uise the requisite components, but in his failure to secure 

 a uniform mixture. 



It is of interest to note how closely the system of valuations, based 

 upon the wholesale prices of raw materials in the principal markets 

 during the most important buying season and upon certain average 

 allowances for expense and profit on the part of the mixer and jobber, 

 coincides with the retail prices later ascertained. A comparison for 

 several seasons past is given below.
