In the old days, you would have one lawyer to handle everything: speeding tickets, buying a house, contracts, litigation, real estate, copyrights, leasing, entertainment, intellectual property, forensic accounting, criminal offenses... the list goes on. Now, you have to have a separate lawyer for each one of those categories!

Mark Hopkins was one of the truest and best men that ever lived. He had a keen analytical mind; was thoroughly accurate, and took general supervision of the books, contracts, etc. He was strictly the office man, and never bought or sold anything.
