The "tugas" or molave trees were used by the ancient dwellers of the island in making posts or "haligi" of their houses because of its strength and durability that could withstand and struggle against strong typhoons and "habagat" and was proven by the house of "Totang" built near the artesian well of Cang-igdot. Most of the patriarchs of the island made the "tugas" trees to a wooden plow or "tukod" to cultivate the rocky soil for farming using mainly "toro" or male cattle to pull it through the sticky and hard rocky soil. However, before the discovery of making "tugas" as the foundations of their house, the primitive Siquijodnons dwelt in the caves as evidenced by the pottery and old tools like stone grinder or "liligsan" excavated by Mitring from the 3 caves of Sam-ang.
