26 WHY TREES DO NOT BEAR 
Other Insects. Very little pollination is due to the wind. Most 
of it is carried by insects, and in order to secure thorough pollination 
alternate varieties of the same kinds of fruits should be planted every 
third or fourth row. 
Blossom Injury. Trees are sometimes supposed to be self-sterile 
when the lack of fruitfulness is really due to some other cause. Blossoms 
may appear perfectly normal, but on close examination it will be seen 
that the vital parts have been injured by frosts; a drying wind will some- 
times damage them to such an extent that proper fecundation is pre- 
vented. 
Rapid Growth. Where the growth is too rapid, trees often fail to 
form fruit buds. To make trees bear when tardy coming into fruiting, 
in June, when sap is in its highest flow, take out strips of bark from 1 to 
2 inches wide, pointed at the ends, extending from the ground almost to 
branches. Always leave intact, around entire trunk of tree, alternating 
strips of bark about the width of the strips taken off. New bark will form 
quickly, without injury to the tree, yet a check will be given that will 
cause formation of bloom buds. This plan is safer than root-pruning or 
girdling. 
Another method is summer pruning, when the trees are in full leaf. 
J. H. Hale Peach Fillers in Baldwin Apple Orchard. 
The above shows the late Mr. J. H. Hale In one of his orchards at South 
Glastonbury, Conn. On the ricfht side of the picture is an apple tree loaded 
with prime Baldwins; on tlie left a "J. H. Hale" peach tree "hllcr." Mr. Hale 
believed In making his orchards pay, the greatest possible returns right from 
the start. Tills method of planting peach tallers between the permanent 
apple trees Is described on page 27.
