Such an appointment was sought by Lawrence Washington for his brother George. It shows what must have been the maturity of mind of the latter, and the confidence inspired by his judicious conduct and aptness for business, that the post should not only be sought for him, but readily obtained; though he was yet but nineteen years of age. He proved himself worthy of the appointment. He now set about preparing himself, with his usual method and assiduity, for his new duties. Virginia had among its floating population some military relics of the late Spanish war. Among these was a certain Adjutant Muse, a Westmoreland volunteer, who had served with Lawrence Washington in the campaigns in the West Indies, and had been with him in the attack on Carthagena. He now undertook to instruct his brother George in the art of war; lent him treatises on military tactics; put him through the manual exercise, and gave him some idea of evolutions in the field. Another of Lawrence's campaigning comrades was Jacob Van Braam, a Dutchman by birth; a soldier of fortune of the Dalgetty order; who had been in the British army, but was now out of service, and, professing to be a complete master of fence, recruited his slender purse in this time of military excitement, by giving the Virginian youth lessons in the sword exercise. Under the instructions of these veterans Mount Vernon, from being a quiet rural retreat, where Washington, three years previously, had indited love ditties to his "lowland beauty," was suddenly transformed into a school of arms, as he practised the manual exercise with Adjutant Muse, or took lessons on the broadsword from Van Braam. His martial studies, however, were interrupted for a time by the critical state of his brother's health. The constitution of Lawrence had always been delicate, and he had been obliged repeatedly to travel for a change of air. There were now pulmonary symptoms of a threatening nature, and by advice of his physicians he determined to pass a winter in the West Indies, taking with him his favorite brother George as a companion. They accordingly sailed for Barbadoes on the 28th of September, 1751. George kept a journal of the voyage with logbook brevity; recording the wind and weather, but no events worth citation. They landed at Barbadoes on the 3d of November. The resident physician of the place gave a favorable report of Lawrence's case, and held out hopes of a cure. The brothers were delighted with the aspect of the country, as they drove out in the cool of the evening, and beheld on all sides fields of sugar cane, and Indian corn, and groves of tropical trees, in full fruit and foliage. They took up their abode at a house pleasantly situated about a mile from town, commanding an extensive prospect of sea and land, including Carlyle bay and its shipping, and belonging to Captain Crofton, commander of James Fort.
