Brush pollinating is often most practicable when many blossoms must be pollinated in a short time. For our common trees however, some work- ers use the thumb or forefinger. As to the percentage of successes, seven pollinators of placed their averages variously at from 50 per cent down. "Some Phases of Pollination" were presented by Prof. N. O. Booth. The period during which fresh pollen is available for study may be lengthened by forcing twigs in the laboratory. If pollen is taken from the orchard at the normal blooming season it is advisable to take twigs with still unopened buds and let them open indoors. This as- sures freedom from foreign pollen. Pol- len of the same variety differs greatly in germination when the trees are grown under different conditions. Determina- tions of the percentage of the germinat- ing pollen is an index to the capacity of such trees for self-pollination in such localities and hence for planting in solid blocks. Very few apple varieties have the pollen all good and none so far all bad, most varieties showing different proportions of mixed forms. Pollen from the same tree may differ with the condition of the tree. Tompkins King and Esopus Spitzenburg among others have notably weak pollen and are suc- cessfully raised only in neighborhoods where conditions are favorable for pol- len production. Varieties with particu- larly strong pollen, as Jonathan and Rawle's are of wide adaptation and are often liable to overbear, the fruits being consequently under size. Prof. Fred. W. Card presented a sym- posium of experience as to the "Ad- vantages of Double
