Appendix A. 



Inö Tadayoshi, the Japanese Surveyor 

 and Cartographer. 



Ino ((n-igiijiilly Jimbo ) Kageyu* was born in 1744 in a small 

 village called Sawaraniura in the province of Shiniosa, rfapan. InO 

 Avas the name he acqnired by marrying into a family, in accordance 

 with the very nsnal Japanese custom. 



His father-in-law was a sake brewer, coiiducting a business which 

 had descended from father to son for many generations. On his death, 

 affairs were found to be in a very bad state. Inö thereupon aj)plied 

 himself diligently to the business, and through his untiring efforts, 

 combined with strict economy, he gradually amassed considerable 

 wealth. In his fiftieth year, that is about 1794, he transferred the 

 whole business to his S(m and began his sciei:itific career. 



Astronomy was the study to which he devoted himself. The 

 books at his disposal were all in Cliinese and contained many obscure 

 passages which he in vain tried to understand. Ultimately he made 

 his way to Yedo, and sat at the feet of the Takahashis, father and 

 son, astronomers to the Shogun. The elder Takahashi died in 1804, 

 and it was with the younger Takahashi that Inö had most to do. 

 Certain letters written to him by Inö still exist, and their style is 

 such as would naturally be used by one addressing a former teacher. 



In 1800 Ino set out by permission of the Government, to survey 

 the Island of Ezcjt at his own expense. In the following year he

 some pronounce it. 



t In the earlier pages of this paper, the more familiar spelling Yezo is inadvertently 

 used. Ezo, however, is better phonetically, and is the spelling sanctioned by theltomani- 

 zation Society of Japan. As the foruier name of Tokyo is quite obsolete, it is best to 

 adhere to the western historical spelling Yedo — although it too should bo Edo.
