RIDDLING. Another name for sifting. 



RIDGING is digging the soil into parallel ridges in 

 such form as to expose it thoroughly to the action 

 either of the atmosphere or of frost. 



RIDGING-OUT. Planting out Cucumbers and Pump- 

 kins in the open-ground beds. Ridring, however, should 

 not be confined to the winter, for in summer the extra 

 exposure to the air and heat is highly promotive of 

 vegetation : it impregnates the soil with oxysen, pro- 

 motes the decay of stubborn vegetable remains, and 

 disturbs predatory vermin. Mr. Barnes says : 

 all ground, as soon as a crop is done with, well trenched, 

 burying all the refuse I possibly can in a green state, 

 casting the earth into rough ridges, tumbling those ridges 

 over with a strong fork on frosty mornings in winter 

 and spring, and during hot sunny days in summer, 

 continually changing the crops ; keeping the hoe at 

 work at all seasons in suitable weather, forking up all 

 odd corners and spare ground without loss of time. By 

 this management, 1 find the ground is alway- 

 condition and never tired by cropping, some j 

 only being exercised in applying such \-. 

 to the soil that have been taken from it, or that are 

 likely to be required by the succeeding crop."
