William Howard Taft,
Hellmich v. Missouri Pacific Railroad Company…
“ It concerns a tax upon telegraph messages paid for by transportation and the question is whether such payment is a charge which can be measured, or measures itself, in money. The most significant evidence that it is appears in the conduct of the parties themselves, for in their exchange of such services they make actual payments to each other in money above a certain amount of business, which amount itself they determine by a carefully kept account of actual services in money figures. ”
