MAIZE. 
For the purpose of investigating the changes in the ash constituents 
of the corn-plant during growth, a number of ash determinations 
were made. August 18, a number of stalks of Waushakum corn 
were selected and labeled as uniform in appearance, each having ap- 
parently two well-developed ears in process of formation. From these 
labeled stalks, commencing with August 18th, when the kernels were 
mostly pollenated, each week a series of five were selected and taken 
to the laboratory. The figures obtained are herewith given: 
August 18th.
