214 IRRIGATION FARMING. 



occupying dry positions. Raspberries can be planted 

 between the rows in an apple orchard, and in this way 

 they would necessarily receive the same amount of irri- 

 gation and cultivation. It is quite essential to irrigate 

 raspberries as soon as the canes are planted, and if an 

 even moisture is kept in the soil throughout the growing 

 season the plants will continue to thrive. It is not ad- 

 visable to irrigate during the week of blossoming, and 

 water must be withheld after the first of September. 

 "We make it a rule to. irrigate raspberries after each pick- 

 ing, as this seems to hasten the maturity of the fruit and 

 develop larger and more salable berries. Black raspber- 

 ries do not demand as much shade or irrigation as do the 

 red varieties. In October the canes should be laid down 

 and covered with earth for the winter, and it is advis- 

 able always to irrigate the entire plantation before the 

 canes are uncovered in the spring, particularly if the 

 ground is dry at that time. 



Blackberries. These canes should be laid down 

 in the fall before all the leaves have fallen, for if delayed 

 until later the canes are likely to snap and break. Irri- 

 gate generally the same as for raspberries, and give heed 

 to plenty of water during the fruiting period. A safe 

 rule at this time would be to irrigate the rows once a 

 wec-k, and keep off the. water just as soon as fruitage is 

 over, in order that the wood may harden preparatory for 

 winter. Too much water during the warmer days of 

 summer is likely to encourage the tendency to rust, and 

 this is a matter that must be guarded against by the 

 careful irrigator. Dewberries are a species of vine black- 

 berries that may be treated the same as the cane fruits 

 only that they are capable of taking more^ater through- 

 out the season, but may require less, as their foliage is 

 calculated to shade the ground in such a way as to pre- 

 vent loss of moisture by evaporation. The dewberry 

 will generally take care of all the water that may be
