PERMANENT-TRESPASSES. When trespasses of one and the same kind, are
committed on several days, and are in their nature capable of renewal or
continuation, and are actually renewed or continued from day to day, so that
the particular injury, done on each particular day, cannot be distinguished
from what was done on another day, these wrongs are called permanent
trespasses. in declaring for such trespasses they may be laid with a
continuando. 3 Bl. Com. 212; Bac. Ab. Trespass, B 2; Id. 1 2; 1 Saund. 24,
