 eretions A great number Of even smaller orange-yelIow speeks will be seen moving over the bark which are the newly-born young still un- or scale secretion and not yet set tied down to feed Their mothers, pale. yellow and inactive. you may find by lifting up the larger gray scales which cover their bodies In the central states at the latitude of St Lofts these young lice are being born as late as November and q few may occasionally be found still later So it will be seen that a decided advantage in fall spray ing as soon as the leaves are off is the easy penetration of the in seeucide to the bodies of the new ly settled insects and to the naked lice still crawling over the bark
 The insecticides most suitable for scale spraying were discussed at some length in the Fruit-Grower for January Those now usually em- ployed are either lime-sulphur so- lutions or sprays containing a low percentage of oil as the killing az ent From all standpoints the standard lime-sulphur was prepared by boiling for three-quarters of an hour in a little water. fifteen pounds quick lime and fifteen pounds sulphur and diluting to make fifty gallons spray mag be re lied upon IT is safe dormant spray Those who do not care to prepare their own iime-sulphur wash will make no mistake in us- ing guaranteed ready-made lime-sul- phur solutions offered upon the market if these commercial lime sulphur are used at strong enough dilution and sprayed thor oGghly
 It cannot longer be doubted that the commercial miscible oil sprays are very effective scale killers. There are several reliable brands upon the market which for con venienee of handling and effective ness cannot be exeelled by lime sulphur preparations. They must be used with great care, howev- CT, to avoid danger to the trees. Oil sprays at too high percentages or in excessive amounts are risky to use on fruit trees In the opin- should use commercial miseible oils, such as Scalecide and Target Brand Scale Destroyer. at the strength rec commended by the manufacturers, which is usually not stronger than l part miscible oil to 20 parts of water. and then apply as very fine mist and not in amounts suf- fieient to flood the tree bases. Lime sulphur solutions should be applied through coarser noZzles and more liquid may be applied per tree with no danger of injury. Neither the lime-sulphur nor the miScible oils should be used before the leaves gre off in the fall and all growth for the season over. This will be late in October or early Tn and according to kind. age and con dition of the trees. Thoroughness of applications is the essential de- tail Whether the spraying is done with power sprayer or barrel pump, every portion of the bark should be wet The spraying should be done from all sides. The tips of the =twigs are often missed when spraying These are the tenderest parts and very often have the most living scales attached to them.
 The time to take this pest in hand Is before the shrubs and trees become badly infested in fact when it first makes it's appear anee. Trees which had but q trace of scale this spring may be badly infested and need spraying this fall. Now is the time to get ready for business. The only fruit grow CT who will be able to appreciate the blessings" of having no San Jose scale is he who makes spray ing a regular orchard practice.
