A fruit tree at this stage of development can- not stand being smoked like a ham, so it is important that the heaters burn the fuel with a good degree of cumbus- tion. The latest and much approved types of orchard heaters are constructed with dampers. This improvement permits of regulating the amount of heat necessary to combat the temperature upon a par- ticular night and thus works a big econ- omy in the saving of fuel oil as it is both useless and impractical to burn the heaters at full blast when the temp- erature has only reached twenty-five degrees. In case the succeeding night the temperature falls to 20 degrees it would be necessary to apply a greater amount of heat and the dampers could be adjusted very quickly to offset the Continued on page 38. Results of Pollination Studies at Idaho University By C. C. Vincent, Horticulturist. University of Idaho, Moscow, Idaho THE subject which has been assign- ed for me to discuss, "Orchard Pol- lination," is one which has re- ceived considerable attention at the Idaho Experiment Station for the past ten years. The original problem, Apple Breeding, has had to do with the improvement of orchard fruits and in the investigating of this phase of the work, certain problems have been en- countered, which it is hoped will prove of interest and value to all investigators in a similar field as well as to practical orchardists of the Pacific Northwest. Self-Sterility an Orchard Problem. One of the first problems in orchard
