Diseased Plum Leaves. 



969. Sir,— In July, '96 I found the 

 leaves on one branch, of several plum trees, 

 looked as though they had been painted with 

 exceedingly thin white paint. In August 

 they became spotty and ragged and fell otl' 

 early in September. This year all the leaves 

 on those trees are diseased with the same 

 thing. I enclose a sample of them and wish 

 you would be kind enough to tell me what 

 ails them. 



/?efi/y by Mr. John Craig, Central 



Experhnental Farm, Ottawa. 



The plum leaves forwarded by Mr. 

 Magor are affected by a leaf rust known 

 as Puccinia pruni-spiiiosa. They are 

 also affected to some extent by the leaf 

 form of fruit rot — Monilia frudigena. 

 Plum foliage has been very generally 

 injured by these two diseases the present 

 season. Also by Shot Hole fungus, 

 another very injurious trouble. All 

 these diseases may be prevented by 

 timely spraying with Bordeaux. It will 

 pay growers to use Bordeaus mixture in 

 their plum orchards much more freely 

 than they have done so in the past. 

 Loss of foliage means a depreciation in 

 the quality of the fruit, and much of the 

 fruit this season is both undersized and 

 poorly coloured. This is principally on 

 account of the falling off of the leaves 

 early in the season. 



outdoors. I tried it with a few baskets 

 this fall, and was more than pleased with 

 the result. 



Ripening- Tomatoes. 



Mr. C. \\. Young, of Cornwall, writes : 

 — It is too late to be of use this year, 

 but the best way to ripen tomatoes is in 

 a cold cellar, without much light. They 

 ripen solid, with good color and flavor, 

 while if put in the sun, as is usually the 

 case, they are watery and without full 

 flavor. This was given me by a friend 

 from the Northwest territories, where it 

 is usually impossible to ripen tomatoes
