"Col. Bachelder:—I have examined your beautiful drawing of the Battle-field of Gettysburg and vicinity. The certificates of Gen. Meade and the Corps Commanders, which appear on its face, establish its accuracy on the highest authority. Your personal explorations, and your inquiries of all the commissioned officers in command of the Union Army, and of the Confederate officers made prisoners, have furnished you means of information not possessed, I imagine, by any other person. Such opportunities of observation as I had during three days passed at Gettysburg satisfy me of the fidelity of your delineation of the position of every regiment of the two armies on each of the three eventful days. * * * * I may add, that the engraving is beautifully executed and colored. Wishing you ample remuneration,
"I remain sincerely yours,
"EDWARD EVERETT."

"Mr. Jno. B. Bachelder:—
"Dear Sir:—I am exceedingly gratified with receiving a finished copy of your print of the Battle-field of Gettysburg. I am familiar with your long and untiring labors in all the fields where truth could be reached, and know that your efforts were crowned with a success that leaves nothing more to be desired. You are authorized to add my name to those who bear testimony to Its accuracy.
"Very respectfully your obedient servant,
"G. K. WARREN.
