On the same subject.
These three letters all relate to the same subject as the two preceding ones—the formation of a navy, and the rendezvous of ships and sailors at Ravenna on the Ides of June.
The Count of the Patrimony is courteously requested to see if there is any timber suitable for the purposes of the navy, growing in the royal estates along the banks of the Po.
The Sajones are ordered in more brusque and peremptory fashion: Gudinand to collect the sailors at Ravenna on the appointed day; and Avilf to collect timber along the banks of the Po, with as little injury to the Possessors as possible (not, however, apparently paying them anything for it), to keep his hands clean from extortion and fraud, and to pull up the stake-nets in the channels of the five rivers mentioned in Letter 17; 'for we all know that men ought to fish with nets, not with hedges, and the opposite practice shows detestable greediness.'
