The experiment stations of the great States of Illinois, Ohio, Pennsylvania, Maryland and New Jersey have made exhaustive experiments with this material, and their bulletins may be had by any farmer desiring them, showing that this material has given results that prove it to be more valuable for many soils than the acidulated phosphate. The great State of Tennessee, on the other hand, without any practical experiments to back it up, in the face of the opinions of some of its most eminent chemists and experts, continues on its statute book an absolute prohibition against the sale of this material within its borders. Mr. Cyril Hopkins, of the Illinois Experiment Station, says that the discovery of the Tennessee phosphate deposits is the greatest thing that ever happened for the farmers of Illinois. Each year many carloads of this material are shipped into other States and wherever it has been used its use is spreading, yet these people have to pay more in freight alone than it would cost the average Tennessee farmer at his farm. Immense deposits of this rock exist in Tennessee high enough in grade to meet the requirements for direct use, and if this prohibition were removed, almost every county seat in the sixth and seventh congressional districts would have phosphate mills to supply the local trade, just as they have flour mills. The next Legislature should certainly correct the errors of the past by allowing the Tennessee farmer to exercise the same amount of free agency, common sense judgment as his fellows of the other States. The principal mines in Tennessee are shown in the table on the following page:
