 For, the prevention of 4fab and rot of peaches, 1t. is as a rule desirable to give three sprayings. as follows: First. shortly, after the blossoms have fallen
 tAfay 10 to May 26); second. about
 three or four weeks later 0une to June 15J; and thifd. about one month sprayinge can be given omit the first.
 On the whole. self f-bofled lime sui- phuf pE<hes 50 fox be the safest and mott .fe3z1t5f4 peach spray. and this iS recomnaended. Good results have been obtained with some of the. commercial lime sulphurs. and they are much more easily handled. There is, however, some danger of spray injury, especially with certain brands. If commercial lime-sulphur is
 used, strength of not greater than 1-160 without poison is recommended.
 As lead arsenate has done little to prevent curculio Ahd as it seems to increase the danger VI SpIAy AuJuEys We advise leaving out the lead arsenate unless there is considerable danger of sawfly injury. when it can be added in the second spraying, the same as for apples.
 PEARS AND OUNCES.
 Since pears are not generally. seri- iously injured by fungi or insects in this state, they frequently require no protection by spraying. Bordeaux has [proved very effective spray in the past, and as we saw. no special sadvan- |.tage from -the other sprays tried, we are still inclined to recommend 1t. es- pecially when used against pear scab. However. we believe that less leaf in- jury will result If the weaker solution 1-4-50, is used after the first treatment. Therefore we recommend the same strengths, and number and times of treatment- with Bordeaux as for apples. l. We would also recommend the same treatment for the quince. since it is even less liable than the apple to suf- fer iujury from Bordeaux on either leaves or fruit. In eases where the quinces tend to rot in the fall, start ing at the blossom end through the levfdent opening in the calyx, 1t may be well to give a fourth spray with weak Bordeaux about month after the third, or about the middle of July " ed of all dead branches, as these car fy over the black rot fungus. To pro- tect tho Quinces from rust evidently requires that they be coated continu- ally with a spray from the time the leaves unfold to the middle of July, taking special care to protect the young fruit and branches. where this
 trouble develops most frequently.
 CHERRIES AND PLUMs.
 If the trees suffer from black knot.
 the knots should be cut off thoroughly
 by the first of April and destroyed.
 If the trees need spraying for San Jose
 scale, the treatment should be made
 with commercial lime-sulphur, 1-S, in April, just before the buds begin to
 swell. as this may help to kill the spores of the black knot. and also will take care of any leaf curl or pocket that. may appear.
 As certain varieties of cherries and plums. especially the latter. are sensi- tive to spray injury as the peach. 1t Is best to use {. only self-boiled ltme-sul- phur. S-s-5O, for summer spraying. If commercial lime-sulphur is used, t should not be stronger than 1-150. ana without poison.
 As a rule, three summer treatments are desirable. and these may be given somewhat according to the fungous
 
 of ripening of the fruit. As a rule, the first treatment should be given on the leaves as soon as they reach ma
 turity. somewhat near the middle of
 May (the earlier the better, for black
 knot and anthracnose). The second should be made on the young fruit from the first to the middle of June. according to it's size and the time of its ripening. The third should be made
 usually a week or ten days before the
 fruit ripens. This will vary from the
 latter part of June, for cherries, to
 about the middle of July, for most of the plums. With early ripening fruit.
 the second and third sprayfngs thus come close together. before picking.
 when used against brown rot. If an-
 thracnose or black knot are the chief
 troubles, it may be we'll to defer the
 third treatment until just after the cherry harvest. AS the cherries and
 plums are smooth fruits, the spraying
 may be made within a week or ten days of picking time, especially if rainy, since the sediment does not adhere to
 tp these so readily as to the hairy
 peaches.
