and the very young leaves become infected, if weather favors, just 

 as* they are burstiug fioni the leaf buds. The disease can be con- 

 trolled by spraying the trees with a good fungicide before the buds 

 swell. Where Scale is to be combated, the strong lime-sul])hui', 1.03 

 specific gravity, used for this jjurpose will control the Leaf Curl if 

 ai»i»lied at tlie time indicated. If it is not necessary to spray for 

 Scale, economy in mateiials, and as good results, can be secured by 

 diluting to 1.02 sp. gr. ; or Bordeaux mixture, u-3-50 can be used. 



Teach Scab or Black Spot is characterized by small dark spots 

 on the fruil. When numerous, they coalesce to form a black area, 

 under which the liesh is hard and insipid, and often traversed by 

 cracks. The tiouble is worse in moist than in dry situations and 

 seasons, and on late than on early jjeaches. 



Peach Brown Rot causes the familiar rot of peaches usually as 

 they approach maturit}'; and at times it attacks new wood growth, 

 producing Twig Blight. It is greatly favored by warm, moist 

 weather. The old brown rotted peach mummies of the preceding 

 year are the common source of new infection, although the ability 

 of the fungus to attack cherries and plums and other fruits, gives 

 a good chance for the spores to become widely distributed before 

 the peach season begins. This rot and Peach Scab can be con- 

 trolled best by using the self-boiled lime-sulphur preparation, de- 

 vised by W. M. Scott and made by stirring in sifted sulphur with 

 slaking lime so that the heat developed in slaking will do all the 

 cooking. The proportion to use is 8 pounds of sulphur and 8 pounds 

 of best stone lime to 50 gallons of water. Only enough water is 

 added at first to cause even slaking, and the necessary cold water 

 is added immediately afterwards, so that the cooking will not be 

 too prolonged. No artificial heat is used. This self-boiled prepara- 

 tion is applied to medium maturing varieties of peach (1) four weeks 

 after the petals fall, and (2) four or five weeks before the variety 

 i;5 expected to ripen. The first application should contain arsenate 

 of lead, 2 pounds to 50 gallons, for curculio, and the second should 

 be applied lightly and as a fine mist to avoid coating the fruit with 

 a heavy sediment that may not weather off before marketing. Late 

 varieties in seasons favorable for rot, may require an application 

 between (1) and (2); and on early varieties (2) should be omitted. 

 Concentrated lime-sulphur, diluted to 1.003 or 1.002, avoids the 

 staining of fruit, but is less effective, and there is some risk of leaf 

 injury from its use.

Gentlemen of the Horticultural Society: — If yesterday morning 

 you had me in the middle of the barrel, this morning I was booked 

 TO come between the Law and Gospel, Professor Surface and Mr. 

 Hale. I will talk to you first about blackberries. I have raised them
