3 lime, 50 water. Then as the fruit approaches maturity the 

 lime sulphur solution i pound to 50 gallons of water must be 

 used. The black knot fungus should be cut off as soon as 

 it appears, and if large wounds are made on the sides of the 

 branches they should be painted with linseed-oil paint with 

 a little kerosene in it. If the plum-curculio is abundant, 

 it should be destroyed by spraying with lime sulphur 

 solution I to 50 of water and 3 pounds of arsenate of lead. 



Thorough cultivation or an abundance of plant-food 

 rich in hme, potash and phosphoric acid must be given, 

 especially when the trees are heavily loaded with fruit. 

 Thinning must be practised to improve the size and quaUty 

 of the fruit and save the trees from being injured by over- 

 bearing. The fruit should be allowed to become very nearly 

 ripe upon the trees before picking for the best quality, 

 though for canning purposes they are sometimes picked as 

 soon as fully grown and well colored. 



The varieties that may be recommended are the Bradshaw, 

 Lombard, Imperial Gage, Green Gage, German Prune 

 (Fellemberg), and Damson of the European plums, and the 

 Wickson, Abundance, Burbank, and Satsuma of the Japanese 

 plums. The last-named variety is valuable only for canning. 



In the Mississippi Valley States where the above classes of 

 plums do not thrive varieties of the native plums should be 

 planted. Among the best of these are De Soto, Hammer, 

 Hawkeye, Maquoketa, Miner, Pottawattamie, RoUingstone, 

 Surprise, Wayland, Wild Goose, and Wyant.

Two or three quince-trees in the home garden will be often 

 a source of much satisfaction. If there is a low place 

 about the grounds, yet where there is no standing water 

 with especially rich soil, the quince will succeed under such 

 conditions; 12 X 12 feet is a good distance for planting,
