Samuel Freeman Miller,
State Tax on Railway Gross Receipts…
“ It is conceded that railroads may be taxed as other corporations are taxed on their capital stock, on their property, real and personal, and in any other way that does not impose necessarily a burden on transportation between one State and another. But a railroad or canal company differs from corporations for banking, insurance, or manufacturing purposes in this, that while their business is only remotely, or incidentally, connected with commerce, the business of roads and canals, namely, transportation of persons and property, is itself commerce. ”
