The Titus County Court House was destroyed by a fire of suspicious origin in 1895. In that day, the threat of fire was the largest danger to the town's existence. There were no water mains or fire hydrants, and no organized fire department to fight the fire. Water had to be drawn in buckets from wells located on and around the public square and carried and thrown onto the fire. Flaming embers from one building could ignite other buildings, which often led to the loss of entire blocks or even entire towns. There was no way to fight large fires, and several buildings on the east side of the square also burned. Two buildings at the north end of the public square on what is now Jefferson Street between East Second and East First Street burned down. The fire then jumped several buildings south and began burning in the Caldwell-Carr Building's attic, but was extinguished without serious damage. Charred rafters can still be seen in the attic.
The Temple Masonic Lodge, which was located on the north side of the square, burned on November 14, 1907, leaving the lodge without a meeting place. Mr. Caldwell, who was a lodge member, along with Mr. Carr, sold the Caldwell-Carr Building to the Temple Masonic Lodge on March 9, 1908. Temple Lodge No. 70, Ancient and Accepted Masons owned and used this building from 1908 until the 1970s, and the building became locally known as The Masonic Lodge building due to their long occupancy.
The Caldwell-Carr Building's design fulfilled the Masonic Lodge's needs very well because it had a second floor to use as a meeting hall. Masonic requirements stated that they could not hold their meetings on a first floor. The ground floor was used for social activity, and later rented out to provide income. The separate exterior door leading upstairs allowed members to come and go without disturbing the downstairs occupants. The stairs' winding design was in keeping with the Masonic Lodge's use of winding stairs patterned after King Solomon's Temple.
The Masonic Lodge rented their building's first floor for many years. Throughout the years, it was inhabited almost exclusively by grocers. Brown's Plain and Fancy Grocery, owned by the Brown Family of Mount Pleasant, was the first to rent the Masonic Lodge's ground floor.
Later, Wilson Jones and Ed Jones, brothers from Gilmer, Texas, moved to Mount Pleasant and opened the Jones Grocery Store, replacing Brown's as a ground-floor tenant. Wilson and Ed Jones soon dissolved their partnership, but Wilson Jones continued the grocery business in the same location. His grocery store soon became Mount Pleasant's first Piggly Wiggly Grocery Store.
Mr. and Mrs. J. A. Black were the next grocery merchants to rent the Masonic Lodge building's ground floor for the Black Grocery Store. Mr. Black was also a city Alderman from April, 1908 to April, 1915.
