all possible-dirt, they apply a magnifying glass to the microscopic blots in the grandest struggle of the war, and while unspairingly baiting the seniors of the garrison over small trifles-very often invented and always exaggerated— they leave themselves no time to notice and reward the gallant deeds of those who took an actual part in the defence.

In conclusion, as the name of Tretyakov is so inseparably associated with that of Visokaya Hill, the author adds the following short note on his previous career:

General Tretyakov, at that time a young Sapper officer, earned considerable distinction during the Siege of Plevna. During the China War, at Hunmir, a small Russian force, consisting of two companies, Fifth Regiment, and a company of Sappers, was attacked unexpectedly by large masses of Boxers, but was saved by the courage and resourcefulness of Colonel Tretyakov, who threw himself forward, leading on his men, who were paralyzed from surprise, and finally dispersed the Boxers. Finally, at the Battle of Kinchow, he and his regiment greatly distinguished themselves, and sustained the attack of three Japanese divisions.

THE WORK OF THE CORPS OF ENGINEERS

OHIO NATIONAL GUARD*

AT CAMP OF INSTRUCTION, FORT BENJAMIN HARRISON, IND., SEPT. 1ST TO 10TH, 1910

HEADQUARTERS CORPS OF ENGINEERS,

OHIO NATIONAL GUARD,

Cleveland, Ohio, October 25, 1910.

THE ADJUTANT GENERAL OF OHIO,

COLUMBUS, OHIO.

SIR: I have the honor to submit the following report on the tour of duty performed by the Corps of Engineers of the Ohio National Guard at the Camp of Instruction, Fort Benjamin Harrison, Indiana, from September 1st to September 10th, 1910, inclusive.

For the benefit of engineer troops of the organized militia, a progressive course of instruction and exercises in military field engineering had been prepared by Maj. Thomas H. Rees, Corps of Engineers, U. S. A., Chief Engineer Officer, Department of the Lakes.

To assist in carrying out this course and to provide a competent corps of instructors, Company I of the Third Battalion of United States Engineers, under command of Capt. W. G. Caples, Corps of Engineers, U. S. A., had been ordered from Fort Leavenworth, Kansas, to Fort Benjamin Harrison. This company, which is maintained at the war strength of 151 men, had been at Fort Harrison a week before the arrival of the Ohio Engineers, and had established for itself the most complete and sanitary camp I have ever seen. The Ohio battalion was located alongside of this company, and was particularly fortunate in having the benefit of this splendid object lesson.

Captain Caples was detailed as Chief Engineer Officer of the camp and also as Instructor of Militia Engineer Troops. The two commands worked together constantly during the encampment, and mingled together socially when not on duty.

The course of instruction began Friday, September 2d. A detail consisting of Captain Troyan, Lieutenant Bradshaw, and sixteen men was assigned to reconnaissance work. A number of the

best sketchers of Company I, United States Engineers, were assigned as instructors. This detail devoted practically all the time during the encampment to sketching and map work.

The battalion was formed at 7.30 a. m., and marched to the northwestern corner of the reservation in the vicinity of Fall Creek, where, under the supervision of Captain Caples, Lieutenant Thomas, and details from Company I, United States Engineers, work was begun making gabions, fascines, and hurdles to be used as revetting material for the field work later to be constructed. Each company was required to cut and assemble the material for and construct two gabions, seven fascines, and ten hurdles. Permission to cut the necessary material had been secured from Brigadier-General Hodges, commanding Camp of Instruction, and the work proceeded without delay. A section of woodland, within which the material was to be secured, was assigned to each company. Details were made to cut the material, other details to carry it to a designated place, where still other details proceeded with the construction of gabions, fascines, and hurdles. At mess time the fourmule escort wagons provided by Company I, United States Engineers, were loaded with the completed material; the battalion reformed and, followed by the wagon train, marched back to camp, where the material was unloaded. This work occupied all of Friday and the forenoon of Saturday, when a sufficient amount of revetting material had been provided.

Saturday p. m. was given to the construction of a standing trench. The battalion, together with a detail from Company I, was marched to a slight elevation just northwest of the camp site, where the trace of the work was laid out. The trench was to be 2 feet wide, 3 feet deep, and 120 feet long. The main arm of the work was to be 90 feet long, and was to command the ground to the north. The short arm was to be 30 feet long and form an angle of 120 degrees with the longer arm, and command the ground to the northwest.

The tool wagons were brought up, tools issued, each company divided into two reliefs, and the work begun. All sod was removed for a space of 9 feet in front of the trench, and preserved to conceal the excavated earth. The work was to have a command of 1.5 feet, and the exterior slope of the parapet was to be 1 on 6. There was to be a berm, or elbow rest, 8 inches wide along the whole front of the trench. When the excavation was finished, the parapet was completely covered with the sod which had previously been removed, and was then practically invisible at a distance of 150 yards in front.

While the trench was being dug a detail from each company was constructing a belt of high wire entanglement about 200 yards in length by 12 feet in width around both arms of the work and about 50 yards in front of the same. This entanglement was constructed of barbed wire, and consisted of one main course of four wires, very similar to a wire fence, on each side of which were constructed aprons at an angle of 45 degrees, each one of which carried four
