major

The officer walking beside Gen. MacArthur is Maj. Gen. Richard K. Sutherland, who was Gen. MacArthur's chief of staff.

It's interesting that MacA has no belt on his coat, and five gold buttons (which he was allowed to do as a general officer). Note the standard officer's uniform worn by Sutherland next to him.

I am told by good authority that it is not General MacArthur in the pic above

This is appears to be (then (1921?)) Major Harry L. Smith (United States Marine Corps). He earned the Navy Cross for valor during the Great War and was quite the marksman. See information regarding Smith and his Marine Corps career at this site describing his since-sold USMC Marksmanship badge: 1914 USMC OFFICER ENGRAVED EXPERT USN SHOOTING AWARD MEDAL, FAMED USMC SHOOTING INSTRUCTOR & 1924 OLYMPICS HAITI COACH This is a historical engraved medal named to one of the top shots ever in the Marine Corps, Harry L. Smith. Smith served from 1909 to 1945 in various capacities but is most famous for being captain of the US Marine Rifle Team in the 1920's and winning multiple shooting championships. In 1924, along with Douglas MacDougal (leader of the Guarde D'Haiti and later general, see photo below), he trained and led the first ever Haitian Rifle Team into the 1924 Paris Olympics where the team won the bronze medal. The Haitians were are part of the Garde D'Haiti or Haitian Gendarmerie that the US Marines trained well into the late 1920's. Smith went on to become a Colonel and train thousands of Marine marksman. In 1919 he was recommended for a Navy Cross by BGen Eli Cole for contributing materially to the war effort, by ensuring that 90% of all recruits coming out of Paris Island in 1918 were qualified with the rifle. The Marines gained a reputation in France and Germany during WW1 for their oustanding marksmanship. He also was influential in the Marine Corps adaptation of the M1918 Browning Automatic Rifle. The medal is a 1914 dated US Navy Sharpshooter medal that has an expert bar attached that is engraved "LIEUT. H.L. SMITH. U.S.M.C.". The planchet is engraved the same. The medal suspension is marked "THE HAYES BROS. CO". A wonderful and attributed medal to one of the best Marine marksmen of all time. Smith served with distinction during the Great War, earning the Navy Cross.

William Alexander Jenyns Boyd (1842-1928), agricultural journalist, schoolmaster and soldier, was born in Paris on 27 November 1842, son of Captain Charles Boyd, 95th Regiment, who had been a lieutenant-colonel in the Anglo-Spanish Legion of 1835, and his wife Mary, née Vachell, an aunt to the writer H. A. Vachell. He was educated in England, in Germany at Mannheim and Bonn, in Switzerland at Cully (near Lausanne) and the Italian School at Zurich, and at the Lycée de Versailles, France. Placed in a Manchester mercantile house while being coached for the army, he preferred to go to sea and, as a teenager, sailed the world in American ships. He migrated to Queensland in 1860 and, immediately selecting a small block at Oxley Creek, grew cotton, arrowroot and rice, and energetically and with characteristic initiative built the district's only cotton-mill. On 2 December 1862 he married Isabella Dawson, who soon began teaching privately; in 1867 Boyd became headmaster of the new West Oxley State School. He was a successful teacher with a progressive concern for individual needs and an 'intimate conversational style'. Boyd began to grow sugar at Pimpama in 1871 and built his own mill. When cane-rust and frosts defeated him, he became headmaster of Townsville State School. He was made 'Occasional District Inspector and Promoter of New Schools' in 1874 and for nearly two years travelled alone through goldfields and remote stations observing northern life and manners. As agricultural editor of the Queenslander from 1874, he published a series of sketches of colonial characters noticed in those years. He resigned from teaching in 1875 to buy and edit the Cleveland Bay Express at Townsville and returned to southern Queensland considerably wealthier in 1878.
