Impressed by the scale of activity unfolding around Titusville, the author tries to describe how profitable oil extraction is. Thus we learn that the daily operating costs of a pump do not exceed $6, the cost of a gallon of oil is 30 cents, a barrel holds exactly 42 gallons, and the daily flow rate of a well is somewhere between 12 and 75 barrels. There we also find a description of how Titusville changed over the year: it got its own newspaper and refinery, the number of buildings doubled, the population quadrupled, a large hotel was founded, and preparatory work for the construction of a railroad is underway. The author's overall impression is that the city resembles a young San Francisco more than a quiet farmers' haven. Special mention is made of the cooperage, which produces about two hundred barrels daily. The product is indeed in short supply!
