Nails are originally packed in kegs of 100 pounds each. 

 In the selection of a nail for any particular use, the length 

 should be two and a half to three times the thickness of the 

 part to be secured. Another element which enters into the 

 choice of a nail is the nature of the wood. A large nail 

 will split, while a lighter-gauge nail, though shorter, will not 

 split and so will hold with its full strength. It is difficult 

 to specify the exact number of nails for any job without 

 knowing the nature of the timber to be used. It is, at times, 

 necessary to drill a hole for a nail in order to avoid splitting. 

 The galvanized and copper nails are used for wood shingles 

 and for slates.
