The general conclusion, therefore, so far as it can be determined by individual testimony, colonial legislative action and the comparative values of Indian and negro slaves, is that Indian slave labor within the territory under discussion was not, as a rule, satisfactory. Mason records that the captives distributed among the colonists as slaves at the close of the Pequot War “could not endure that yoke; few of them continuing any considerable time with their masters”.[1126] Mayhew tells in 1690 of the tendency to run away shown by the Indian slaves of Massachusetts.[1127] Moses Marcy of Oxford, Massachusetts, had an Indian woman sold him by the general court prior to 1747. In that year he was discharged from his bond, she having “made way with herself after having tried to murder her mistress ... run off and not heard from since”.[1128] It is stated that the Indian female slaves of New England could not be taught to sew, to wash clothes, or to render any valuable domestic service;[1129] and that the Indian slaves of Rhode Island “only became efficient workmen under a stern and vigorous discipline”.[1130] Sir Robert Mountgomry, who advocated in 1717 the establishment of a colony south of Carolina, urged the use of indentured white servants, so that there might be “no necessity to use the dangerous help of Blackamoors or Indians”.[1131] The various laws, already discussed in another connection, and the numerous newspaper advertisements show Indian slaves to have been as much given to running away as their negro companions. In fact it seems not unlikely that they were more inclined toward trying to escape, for the possible chance of returning to their own people offered greater inducements for such an act than in the case of negroes. Indian slaves as well as negroes were implicated in the various slave disturbances which occurred from time to time in the different colonies. Though there seems no evidence that Indians were usually more instrumental than negroes in creating these disturbances, yet their not infrequent participation in such events tended to lower the colonists’ estimate of their value, and led to definite legislation seeking, by preventive measures and by decreeing severe punishments in case of conspiracies or uprisings, to avoid the danger which the colonists feared.
