The first diary contains entries from August 11-18, 1853, which discuss a journey from Belmeadto Warm Springs, Bath County, Virginiawith stops at Bremo, Fluvanna Countyand Lexington. During his visit at Lexingtonand tour of the Virginia Military Institute, Cocke saw John B[owdoin Cocke] who had entered V.M.I. as a cadet two weeks earlier. He mentions the many improvements shown to him by Superintendent Francis H. Smith, such as the new society rooms of the cadets, the new wing of the barracks, and the design of the new mess hall. Upon leaving Lexington, he travelled on to Warm Springs, where he mentions meeting his old West Pointinstructor, Edward H. Courteney, currently a professor at the University of Virginia, along with James L. Cabell, another University professor. He mentions the arrival of servants with a carriage buggy and four horses. The next few entries contain brief notes about the weather. The beginning of this diary also contains notes on Warm Springsproperty, the Warm Springs Company(incorporated in 1815), and touches on the subject of slaves owned by the Company, capitol, and acreage, and mentions Brockenbrough, Taylor, and Patterson.

The 1860 diary contains entries from April 25 through May 3, and discusses a meeting in Richmondof the Board of Visitors of the Virginia Military Instituteand subsequent plans and courses of action. The April 26 meeting was held in the office of Adjunct-General William H. Richardson, and was also attended by Col. William McLaughlin, Col. Samuel Downing, and Col. Francis H. Smith. During the meeting, they adopted a resolution authorizing Superintendent Smith to proceed with recommendations outlined in his report to the Board on ["Scientific Education in Europe"] and later submitted to the General Assembly. The Act of March 28, 1860, increased the annuity to V.M.I., and the sum of $20,000 was specifically appropriated for building purposes. Another meeting that afternoon was attended by Gen. George Blowand Col. William H. Paynein addition to the others. There is some discussion of meetings of the Armory Commission consisting of Cocke, Col. Francis H. Smith, and Capt. George W. Randolph. Randolph reported that [James T.] Amesresponded favorably to their proposition and offered to furnish weapons machinery used for rolling [musket barrels?]. On April 27, the Commission discussed plans for organizing and operating an armory, a decision to examine the Springfield Armoryand visit Ames' works at Chicopee, Massachusetts, and the reorganization of the State Armory. [Henry A.] du Pontfurnished a plan and specification for building a powder magazine, and the Commission resolved to purchase $10,000 worth of powder. On April 30, the subjects of the patented breech loading rifle, a new English pistol, and the Massachusetts Fire Arm Companyat Chicopeeare mentioned. On May 1, the Commission toured the Frankfort Arsenalin Pennsylvaniawhere machinery for making musket and pistol percussion caps was seen. The discussion includes costs and operation by steam-engine. Cocke also mentions the "Pyrotechny & Military Laboratory" at V.M.I., and the amount of gunpowder contracted and to be deported to the magazines at Richmondand Lexington. He also notes that du Pont was a classmate of Smith's at West Point, and that he met one of his own classmates, Tench Tilghmanof Maryland. On May 3, the Commission travelled to Springfieldto see Ames in connection with the manufacture of sabers at Chicopee. They met with Major [William Anderson?] Thorntonof the United States Army, who had just completed his inspection of 1,000 cavalry sabers made by Ames for Virginia. Ames agreed to meet them at his works at Chicopee, where the Commission had a tour during which they saw the operation of machinery by water and the machine shops with wrought iron and specimens of hinge castings. Cocke mentions that Ames makes many crossfield guns and howitzers for the United StatesGovernment, and is manufacturing the rifle-musket for the Queen of Spain.
