Pipe, Pipa, in law, is a roll in the exchequer, called also the great roll. See the next article.

Pipe-Office, is an office wherein a person called the clerk of the pipe, makes out leaves of crown-lands, by warrant from the lord-treasurer, or commissioners of the treasury, or chancellor of the exchequer. The clerk of the pipe makes out also all accounts of sheriffs, &c. and gives the accountants their quietus eft. To this office are brought all accounts which pass the remembrancer's office, and remain there, that if any stated debt be due from any person, the same may be drawn down into the great roll of the pipe: upon which the comptroller issues out a writ, called the summons of the pipe, for recovery thereof; and if there be no goods or chattels, the clerk then draws down the debts to the lord treasurer's remembrancer, to write estreats against their lands. All tallies which vouch the payment of any sum contained in such accounts, are examined and allowed by the chief secondary of the pipe. Besides the chief clerk in this office, there are eight attorneys, or sworn clerks, and a controller.
