The mechanical analysis shows that the clay content 
decreases slightly as one goes westward, and this is accom- 
panied by a gradual decrease in fertility. Happisburgh and 
Runton farms are rented at almost twice as much as Catton 
and Antingham, the former suffering less from drought or hot 
seasons, as well as being more productive.
