(c)

by registered or certified mail addressed to his last known place of residence, or

(d)

if such owner has no such residence in such city or town, or cannot be found, and he has no agent or attorney, by affixing a copy thereof conspicuously on such property, between the hours of nine o’clock in the forenoon and four o’clock in the afternoon; if the owner be a corporation, said service shall be made (i) by delivering such copy to and leaving the same with the president, vice-president, secretary or clerk to the corporation, the cashier, treasurer or a director or managing agent thereof, personally, within the state, or
