made to permit greater aeration. In this form, about 

 three pairs of sheaves should stand firmly upon their 

 own bases, while two additional pairs at each end should 

 lean toward the central pairs, and still another single sheaf 

 be added at each end. Two sheaves as cappers are usually 

 placed lengthwise of the shock with their butts pressed 

 together to interlock them. The number of sheaves in 

 this shock will depend upon the length of the two capping

sheaves unless cap sheaves are not used. If there is 

 danger of this narrow shock blowing over, place one or 

 more pairs of sheaves and a single one on each side of it 

 at the middle, with two more cap sheaves as before 

 described, thus forming a cross-shaped shock. The long, 

 narrow shocks are often made in this country and Aus- 

 tralia (Peacock, 1911, pp. 9-10), and are common in the 

 north Caucasus (Fig. 102). Occasionally shocks are 

 protected with several cap sheaves, bound together, 

 placed with the spikes downward (Fig. 103).
