There I had chances to hear from my teachers of the foreign steamers, and sometimes I 'vished to see them. One day I happened to walk on the shore of Y edo Bay and caught a sight of the Dutch warships lying at anchor. They looked so stately and formidable ! When I compared those dignified sea-queens side by side with our clumsy and disproportioned junks, nothing further was needed to convince me that the foreigners who built such war~ ships must be more intelligent and a ~;uperior people to the ,Japanese. It seemed to me a mighty object lesson to rouse up roy ambition to cry out for the general improvement and renovation of my country I supposed the first thing to he done would be to ere~ ate a naval force, and also to build vessels of the foreign style to facilitate the foreign commerce. This new idea prompted me to pursue the study of naviga­tion. " In a course of two years' hard work I finished my arithmetic, algebra, and geometry, and also acquired the rudiments of theoretical navigat,ion ; but my study was sadly interrupted by severe measles. My illness was a very serious one, and utterly enfeebled me.

But this apparent little gain caused me gt·eat loss. "\V eak eyes, headaches, and sleeplessness carne upon me one after another, and I was obliged to give up my studies for some time.
