mixing in tar, is found excellent. If too thin to handle 
conveniently, mix in a little whiting or chalk dust. Sal 
ammoniac or spirits of hartshorn will dissolve the corrosive 
sublimate more easily than the spirit. It is an insecti- 
cide, and when a gallon of soft water is used in place of 
the tar it is a good wash to kill all insects and their eggs 
on the bark. If nothing better is convenient, a little 
grease of any kind will have a good effect on the wound. 
If a limb bleeds when it is cut off, it may be worth 
while to apply Anight’s Composition of four parts scraped 
cheese with one part of shell lime, or other pure lime. 
pressing the composition strongly into the pores of 
the wood. With this he found he could instantly stop 
the flow of sap in the largest branch. The worst time 
to prune is when the sap begins to flow actively in the 
spring. By contact with the air it sours and becomes 
poison to the bark. We ought not to close this topic 
without suggesting, that when the smaller limbs and 
twigs are cut off a good sharp knife is not always the 
most desirable implement to use. It often slips and 
injures what is not intended to be cut away. Small 
limbs can be pruned more rapidly with a good pair of 
shears. 
CHAPTER XII. 
PROMOTING FRUITFULNESS WITHOUT PRUNING. 
1. Tu1s may be done by restricting root growth by 
pruning or cutting in the roots, as described on a former 
page, and need not be repeated here. 
2. Bending down strong-growing branches without 
fruit-buds, has been found to retard the circulation of 
the sap sufficiently to induce fruitfulnoss. Tue pendant 
form becomes fixed by a single scason’s growth, and may 
be so skillfully arranged as to secure symmetrical and
