Frequently the clerk could and did exercise great influence with the justices in the handling of legal matters. As the members of the court were laymen, it often occurred that the clerk was the only person who was learned in the law, and his advice must have been a determining factor in many situations. His tenure in office also strengthened his position of influence, for it was customary to retain clerks in office for long periods of time, during which they had daily contact with the workings of the law and events in the county. Unlike the justices, who came from all parts of the county and seldom were present except on court days, the clerk was much more available at the courthouse, and so generally was the first to hear news from the colonial capital or the outside world. As a result, the clerks of the court were consulted on a variety of matters whenever a justice was not available. Fees charged for performing the various services connected with the work of the court made up the income of the clerk, and occasionally the same person might hold the positions of clerk and surveyor, notary, or special commissioner. Under certain circumstances, clerks also could practice law, and all of these sources combined to produce an income which was for the times comfortable. In the eighteenth century, two significant changes in the law prescribing the clerk's office occurred--it was made a salaried position, and the county court was given full authority to appoint the clerk--but in other respects the office was changed very little either by the passage of time or the transformation from colony to commonwealth. Ranking roughly equal to the clerk in importance to the operations of county government was the sheriff. The office of sheriff appeared when counties began to be established in the 1630's; and until after the War of Independence, sheriffs were appointed by the governor on recommendation of the county court. Almost from the beginning, too, it appears to have been customary to appoint deputies or "under-sheriffs". So it is not surprising to find that after 1661 it was customary for the office of the sheriff to rotate annually among the members of the court who, in turn, appointed their deputies directly. But in the eighteenth century this system proved too disruptive, and deputies were retained throughout several terms of sheriff's appointments.[52] From the beginning the sheriff and his deputies were compensated by fees which they collected for a wide variety of duties. These ranged from tasks connected with execution of the court's orders in criminal cases, to enforcement of the law and administration of the jail. In addition, the sheriff was due a fee from a master whose runaway servant or employee he apprehended and returned, or for collecting private debts or administering corporal punishment to servants for their owners.[53]
