In computing the cost of any engineering project due weight shouldbe given to the effect of chmatic conditions on labor andalso on construction plans. RANGE OF TEMPERATURE. ITie Canal Zone has a moist tropical chmate, modified by oceanicconditions, and therefore showing little yearly and daily variation oftemperature. The nightly average is 71° and the daily about 85° daily range of temperature is greatest in the dry season, for thenthere are few clouds to obscure the suns heat in the day or to absorband reflect the radiation from the earth at night. The highest re-corded temperature over a number of years is 97° F., observed atAncon February 13, 1906, and the lowest 59° F., observed at BasObispo Februa
