Plate 14—Troutman Healers Burning, Showing Method of Reinforcement thermometers used in the test block were very sensitive, and had they been graduated to but 120 degrees in one- degree spaces would have been all that could have been asked. However, we think it best for general orchard use to have a thermometer with some sort of a rigid back. Two types of heaters were used in this test. One was the Bolton or Fresno orchard heater, manufactured by the Frost Prevention Co. of San Francisco, and commonly known throughout the Rogue River Valley as the Fresno pot. However, the present company put it out under the name of the Bolton Orchard Heater. It is of a lard pail type, holding one gallon of oil, and has as its special feature a circle of small holes around the top. They also advocate with this the car- bon arrester, claiming that with it a double burning period may be had with a loss of only ten per cent of the maximum amount of heat produced. That is, the Bolton pot burning four hours without the arrester will burn eight hours with the arrester, and at the same time produce ninety per cent as much heat. This is one of the simplest of orchard heaters on the market today, and is very popular in the Rogue PUver Valley. The other type of heater is known as the Trout- man heater, manufactured by the Round Crest Orchard Heating Co. of Denver, Colorado. The heater has a capacity of five quarts and is circular in form, but differs from the lard pail type in that it has a draft coming through the bottom of the pots and carried to the center of the burning area by a funnel-shaped opening through the center of the pot. One difliculty was experienced with these heaters which was not noticed in the other, and that was in the filling; it was more difficult to pour the oil into the heater without pouring it through the opening in the center. This draft funnel through the center, however, extends to about one inch above t
