Prof played ponies with two accounts, betting one by Mike’s "leading apprentice" system, other by his own "scientific" system. By July ‘75 he admitted that he knew nothing about horses and went solely to Mike’s system, increasing bets and spreading them among many bookies. His winnings paid Party’s expenses while Mike built swindle that financed catapult. But Prof lost interest in a sure thing and merely placed bets as Mike designated. He stopped reading pony journals—sad, something dies when an old horseplayer quits.
