INTRODUCTION. 
In May of this current year, an amendment to the fertilizer 
law of this State was made by the legislature, as a result of which 
the administration of the law was transferred to the Department 
of Agriculture. This Station continues to perform the chemi- 
cal analyses. The analyses published in this bulletin represent 
only samples of fertilizers collected by this Station previous to 
the time the law was amended in May.
