 ten inches through, but such were not durable and soon 

 rotted down. The first improvement was to hew the

the single log pen (see Fig. 28). These sheds fully

 12 to 15 feet wide. A shed 12 feet wide, if built around 

 a pen 24 feet square, has 36 ground tiers 12 feet long, 

 and if the shed is built three tiers high, such a building 

 will provide 118 firing tiers, besides the collar beams, 

 which will be equivalent to 18 additional ones, making 

 136 tiers. A shed so built is capable of holding 2448
