Ammonia. 



§'y8. Sir, — What strength should ammonia be used for spraying ? 



J. E. K. Herrick, Ahbofs/ord. 



Two quarts for twenty-five gallons of water. Ammonia, however, so soon 

 evaporates, that we would commend some other specific washes as more ser- 

 viceable and less expensive. 



Early Potato. 



879. Sir, — What is the earliest potato for market ? 



H., St. Catharines. 



During the past season we have grown Burbee's Early, with much satisfac- 

 tion. It is very early, of fine size and quality. 



Possibly some reader knows an earlier variety still. 



Distance to Plant. 



880. Sir, — What is the best distance for planting plums, pears and cherries in this 

 neighborhood ? 



H., St. Catharines. 



Twenty feet is not too great a distance for all standard pears, plums, and 

 either Heart or Bigarreau cherries. Dwarf pears, quinces and Morello cherries 

 may be planted half this distance. 



THE MINER PLUM. 



Some claim that the Miner plum is a profitable variety, while others con- 

 tend that it did not bear, and they were on the point of digging up the trees 

 The fruit is large; skin, bright scarlet ; flesh, yellow and adheres to the stone. 

 The quality is good, and although the Miner is not invulnerable to the curculio, 

 it does not cause the fruit to drop. 



The tree is a strong grower, and will attain a height of six feet the second 

 year from root cuttings. Owing to its rapid growth it will not bear while young. 

 We are assured by those who have old trees that they have an abundance of 

 fruit every year. We expect to see this variety become quite popular in a few 

 years, as the demand is already on the increase.
