 note = {Starting in the year 1600, for about 150 years, a large number of timbers called Okureki, which were cut into trapezoid cross-sections from the Sawara cypress (Chamaecyparis pisifera), were carried out from the Ohkawara-yama forests in Shinsyu Ohkawara-village. For about 100 years after the Sawara cypress was exhausted, until around 1820, other kinds of trees were harvested to pay tax and to cope with the problem of poverty. These timbers were carried out mainly on the stream of the Tenryu-gawa river. During the 17th and the 18th centuries, those timbers were often lost due to rock slides, floods of rivers and disasters at sea. People recorded the particulars on disasters of timbers precisely in two cases; 1) In 1748, 604 timbers of the tree-species belonging to Abies and Tsuga were swept away by a flood of the Koshibu-gawa and Tenryu-gawa rivers. 2) In 1763, 156 timbers were lost due to strong wind and waves on the coast of the Kakeduka-minato harbor that was at the mouth of the Tenryu-gawa river. This paper describes the contents of those historical documents that recorded these two cases of disasters. Based on these documents, we can understand how dependent the people were on the forest resources in those days.},
