Of these a number of the despatches of Governor Tryon to Lord George Germain, will be found in the Colonial Office Records, under heading “America and West Indies.” Those of 1780, for instance, are indexed No. 189--a bundle which contains some fascinating papers, such as the original reports of spies, a number of these signed by one especially active scoundrel whose signature, A. Z., is frequent, and his suggestions for the confounding of the American forces full of a lively personal interest. On the reports of deserters and spies, many favorable prognostications are founded by the writers of these despatches, and much may be learned of the policy and directions which led to some of the stirring events of that period. Another source of information of a most detailed character is the large collection of log-books of the various war vessels. These were, in those days, kept not only by the Captains, and by the Lieutenants in command, but separate books were also kept by the sailing masters. Of the two former, those of the Lieutenants being practically duplicates of the Commanders’, have been destroyed, but the Captains’ and Masters’ books are preserved. These books are in the original bindings and are of a most interesting character, carefully noting the time and nature of every occurrence in which the ship took part, as well as the surrounding circumstances of weather, sea and course. From them may thus be obtained not only much new information of the details of actions, but confirmative and corrective matters of time and place. In the course of a study of the operations of the British marine in the waters of New York, I found myself confronted by contradictions of a very annoying nature in the published accounts of the events of 1776, but upon reference to these log books many of these points were fully cleared up. Of some of these I hope at a future date to be able to give details, but the purpose of this article being to afford to others the knowledge of the existence and accessibility of the source of this information, I shall here give only the index numbers of the log-books of the most important vessels, which bore a prominent part in the Revolution. The well-known names of the redoubtable men-of-war, frigates, armed brigs and schooners will recall to my readers events in which these took part, and the significant gaps in the logs of some point to the disasters or captures of which they became the victims.
