The 39th parallel of latitude lies just south of Tientsin; followed westward, it crosses the toe of Italy's boot, leads past Lisbon in Portugal, near Washington and St. Louis and to the north of Sacramento on the Pacific. We were leaving a country with a mean July temperature of 80 deg F., and of 21 deg in January, but where two feet of ice may form; a country where the eighteen year mean maximum temperature is deg and the mean minimum deg; where twice in this period the thermometer recorded 113 deg above zero, and twice 7.
