“During the Spanish regime, a part of Cuatro Santos belonged to Tiaong, Quezon (formerly Tayabas). In those days, some men from Lipa decided to make arrangements with the people of Tiaong so that the portion that should belong to Lipa because of the mountain that separates Lipa from Tiaong might be given to Lipa. These men made negotiations with the Tiaong people, and after a long time of negotiation, the Lipa people were successful.
An agreement was made. They decided to meet at a certain place to be the political boundary line between Tiaong and Lipa. A day was set for the rendezvous and both parties started from their respective towns and the point of the meeting became the boundary line. They happened to meet in a brook in the Malarayat Mountain. The parties declared that the brook where they met became the official boundary line. Since that time up to date, that brook has been called the Bulahan Brook. A marker was set to show that the portion east of it was Tiaong and that portion west of it was Lipa.”
“During those days, there was a dispute between the municipalities of Tiaong and Lipa. Tiaong claimed that Cuatro Santos belonged to its jurisdiction. The municipality of Lipa had the same claim. The trouble was brought to the Spanish highest court. The decision was that this place belonged to the municipality of Lipa.”
