true , i have daily contact with the colored stable boys at the local racetrack who freely tell me how their particular horse is doing before i place my bets , with the colored porters who load and unload the luggage of my guests at the train depot and my own suitcases on my frequent journeys to the gay and splendid racetracks of louisville and lexington , the colored shoeshine boys who frequent downtown , and the colored maids , cooks , and butlers of the wealthier homes i am on occasion allowed to be a guest in .
