by John Marshall Harlan, United States v. Union Pacific Railway Company…
“ We perceive no escape from the conclusion that it is entirely competent for congress to add to, alter, or amend the acts of 1862 and 1864, so as to require the Union Pacific Railway Company, possessing the rights and powers of its constituent companies, to maintain and operate, by and through its own officers and employees, telegraph lines, for railroad, governmental, commercial, and other purposes, and to exercise itself and alone all the telegraphic franchises conferred upon it. ”
