Long Description:
The 3rd Corps, 2nd Division, 3rd Brigade was also known as Burling’s Brigade. During the battle of Gettysburg, it served as a member of Humphrey’s Division in the Third Corps, Army of the Potomac. The brigade was commanded by Colonel George Childs Burling (February 17, 1834 – December 24, 1885), a United States Union Army officer during the American Civil War, serving mostly as colonel and commander of the 6th New Jersey Volunteer Infantry. Burling married in October 1862. After the war, he and his wife lived on a farm outside Philadelphia, Pennsylvania. Burling was employed for a time by the Pennsylvania Railroad and died at his home in Philadelphia of pulmonary cancer two decades after the war ended. He is buried in Harleigh Cemetery, Camden, New Jersey, in the Trinity Section, Lot 118.
The Burling's Brigade - US Brigade Tablet is located on the right or northeast side of DeTrobriand Avenue when traveling northwest along the Avenue. The monument is inside on the west side of a perfect circular turn resembling a bowl, near the top part. 
Parking is available at intermittently enlarged shoulder cutouts on the right side of the road. Be sure to keep vehicles off the grass or you will be ticketed by park police. I visited this monument on Thursday, July 5, 2012 at 2:19 P.M. I was at an elevation of 529 feet, ASL. I used a Canon PowerShot 14.1 Megapixel, SX210 IS digital camera for the photos.
The monument work was done under the direction of the Gettysburg National Park Commission (established by the United States Department of War), after they took over the administration of the park from the Gettysburg Battlefield Memorial Association (whose funds had expired) on March 3, 1893, and whose stewardship was then transferred to the National Park Service in 1933) SOURCE. According to the NRHP narrative, this monument was built in 1911 but finished in 1912, which according to my experience is questionable. I can't resolve if the 1912 date represents a completion of the physical construction of the tablet or an installation date. Other sources have it at 1910 & 1912. I don't know if anyone actually kept exact records of when these things were installed.
Draw the Sword, with descriptive help from the NPS site, offers the following description: Monolith consisting of polished smooth sea-green granite pedestal with a square base. Base tapers to a smaller dimension at the tablet. On each pedestal is mounted a bronze inscription tablet describing the movements and actions of the unit. The diamond symbol of the Third Corps appears at the top of the tablet before the main inscription.
One of 74 (or 75 depending who you listen to) Union brigade monuments erected at Gettysburg by the United States War Department to describe the movements and itinerary of each Union brigade of the Army of the Potomac. The monuments were designed by E.B. Cope. Many of the inscription tablets were made of bronze melted down from Civil War cannons. The inscription on this tablet reads:
Army of the Potomac
Third Corps Second Division

July 2 Arrived between 9 and 10 a.m. and joined the Division. Between 2 and 3 p.m. advanced with the Division and was placed in reserve in rear of Second Brigade and soon thereafter ordered to First Division except that the 5th New Jersey supported Battery K 4th U.S. on the Emmitsburg Road. The 2d New Hampshire and 7th New Jersey reported to Brig. Gen. C. K. Graham and supported Batteries in the Peach Orchard the 63d Penna. on the left. The 6th New Jersey went to the support of Second Brigade First Division on its left in Plum Run Gorge near Devil's Den. The 8th New Jersey and 115 Penna. were sent to the Wheatfield to support the right of Second Brigade First Division. The Regiments of the Brigade were severally engaged where assigned and retired at the close of the day with the organizations with which they served.
July 3 In the morning rejoined the Division and was placed in reserve where apparently needed.
Casualties Killed 6 offices 53 men. Wounded 43 officers 333 men. Captured or missing 78 men. Total 513.
There are hundreds of non-sculpted monumentation for the various Confederate States & Union units which fought at Gettysburg. There are about 10 different variations of tablets, markers & monoliths by my reckoning. Six designs represent brigade (2), division (2), corps (2), & army headquarters (2), each different in a subtle way so as to distinguish between armies. Battalion/battery/advance position markers & regimental monuments for U.S. Regulars & Confederate have their own distinct design (2), bringing the total to 10 designs at the battlefield. The bronze tablets were created by Albert Russell & Sons Co. of Newburyport, Mass. The granite bases which accompany the various tablets were created by the Van Amringe Company from Boston, Mass. The cast iron tablets were manufactured by Calvin Gilbert. The 1910 Gettysburg Commission report lists the awarded contracts to these companies (not Gilbert) for the tablets. All of these tablets were designed by architect Colonel Emmor Bradley Cope (July 23, 1834 - May 28, 1927). He designed pretty much every tablet for both the Union & Rebel armies, each one distinct, w/ several different varieties. He is buried in Evergreen Cemetery 
in Gettysburg, as well he should be as this park and most of the things seen here today were designed by him and as such, are his legacy. These monuments were erected just after the turn of the century during the first & beginning of the second decade of the 20th century. Each one has since been preserved or restored at least twice since the turn of the 21st century. The plaques & tablets were erected by the Gettysburg Park Commission (established by the War Dept.). The Gettysburg Park Commission is also referred to as the Gettysburg National Military Park Commission or the Gettysburg National Park Commission, to clear up any confusions, especially my own.
On October 1, 1898, the Gettysburg National Park Commission in a letter to the Secretary of War set gave recommendations for continuing the task of organizing & progressing the work of the Gettysburg National Military Park. Every November they wrote their annual report which outlined the work of the GNPC for that year. The following is an excerpt from that report relevant to this waymark. The link at the end of the paragraph will take you to the entire report. The method of marking the positions of troops on this field, as approved by the War Department, is to place the principal tablet or monument of each command at the position occupied by the command in the main line of battle, and to mark the several important positions subsequently reached by each command in the course of the battle by subordinate and ancillary tablets, with appropriate brief inscriptions giving interesting details and occurrences and noting the day and hour as nearly as possible. SOURCE
Most of the Commission reports have been digitized and can be found HERE. The initial 1893 report up to & including 1921 can be found here. 1922 to 1926 are missing & have yet to be discovered. The years 1927 to 1933 were discovered in 1996 and are also included. To my knowledge this is the most comprehensive list of documents that illustrated the development and formation of the park.
Information about these specific types of monuments:
BRIGADE HEADQUARTERS MARKERS (FOR UNION & CONFEDERATE TABLETS)
Brigade Headquarters (and Confederate artillery battalions, equivalent to Union artillery brigades) are bronze tablets mounted at an angle on a stone pedestal. They are the most numerous headquarters at Gettysburg, with over 70 Union and over 60 Confederate examples on the field. Union headquarters are marked with their corps or service branch symbol (like a cross, clover or crescent moon), while Confederate headquarters are simply labeled "C.S.A.". There are seventy-four brigade markers at Gettysburg honoring the AOP’s various brigades. (Other sources say there are 75). They were built by Albert Russell & Sons Co. of Newburyport, Massachusetts and Charles Kappes. The pedestals consist of sea-green granite with a square 36” x 36” base; they weigh 3500 pounds. On each pedestal is mounted a bronze tablet with rounded corners weighing 300 pounds. There are sixty-four brigade markers honoring the Army of North Virginia's various brigades. They were built by Van Amringe Granite Company (pedestals), Albert Russell & Sons Co., Newburyport, Mass (tablets) and Charles Kappes (foundations). The last was completed in December 1910. The 1910 date is disputed by other sites listing the end dates as 1912. The monuments consist of red circular Maine granite bases 34 1/2 inches diameter and weighing 3,000 pounds. On each base is mounted a 300 pound bronze tablet. SOURCE & SOURCE
