・25日夜間、わが艦は朝鮮の海峡を通過した。日没直後に、日本の海岸が東四分の一北東から東南東にかけて広がり、朝鮮の海岸が北西から北にかけて広がる さまを認めた。海は北東の方角に大きく広がっていくように見えたが、この方角からかなり大きなうねりが来ることがわかり、やはり海はこの方向に広がるので あると確認できた。

南西から疾風、夜は非常に明るかった。追い風を受けて航行、出来る限り縮帆して時速三分の二リユまでしか出ないようにした。太 陽が昇り始めたらすぐに、前日夕刻の測量地点を確認し、朝鮮の海峡の正確な海図を引くためであった。私達の測量はすべてダジュレ氏に委ねられていたが、そ れに基づいて作成される海図の正確さについては、文句のつけようのないものであった。三十分ごとに水深測量を繰り返していて、辿っていくには朝鮮半島沿岸 部のほうが、日本沿岸よりも興味深いように思われたので、朝鮮側から二リユの距離まで近づき、陸地の進む方向に平行して航行することとした。

・ 能登岬の測定によってラ･ペルーズは、この海域の水路測量のために大きな貢献をしたのである。なぜなら、朝鮮や沿海州沿岸との関係における日本の位置 は、これによってかなり画定されることになったからである。彼らは次のように言っている。「大多数の読者にとって、まさに不毛と思われるこの短い鑑札のた めに、我々は濃霧おなかでの困難な十日間の航海を要したのだった。地理学者たちは、われわれがこの時間をよく利用したと考えるだろうが、ただわれわれの広 大な計画が、この沿岸、ことにこの国と朝鮮とを判っている海峡の芯の形を記述するtことが出来たと思われる南へ見勝手いくつかの地点を、調査士かつ測定す ることが許されなったことを遺憾におもうであろう。」、

In the month of March of this year, the gradual increase in the number of the English and French frigates lying in the fine harbour of Hong Kong betokened a speedy termination to the inactivity of the allied squadrons in the Eastern Seas, and once more awakened the sentiments of pride and hope which, since the declaration of war las year, the apparently aimless movements and ill success of our naval forces on the north-eastern shores of Asia had repressed.

Strait of Corea= Strait of Korea today. P8-9.

On the 22nd the Gotto island and rocks were in sight; and, as we still continued to steer northwards, the eager desire of seeing Nagasaki, which we supposed was to be our first port, very soon merged into the greater pleasure of there being less delay in our advance. The air became much cooler and cleare as we approached the Strait of Corea; and, in consonance with the weather, the first whale ship was seen on the same day; and henceforth the eye seldom rested on the water without a serching glance for the traces of spouting of the hotly and far pursued monster of the deep.............................A light northerly wind,"breathing whence it stole those "icy" sweets," baffled our efforts to get through the Straits on the 23rd. We endeavourd to pass between the island of Tsu-sima (sima means island in the Japanese language, and may, therefore, in future stand for its English synonyme) and the peninsula of Corea.

Sea of Japan; P11

The subsequent day, before a fresh southerly wind, we ran into the sea of Japan; and as it was clear, because cold, weather, our consorts and the Sibylle tried their rates of sailing nder the unfavourable circumstances of overloading for the frigate, though so far favourable for Symonite brig and frigate, inasmuch as the sea was smooth: in twelve hours the Bittern had gained six miles and the Hornet two.

P164. The Vincennes was to proceed, via the Bonin Islands, to Loo-choo, the Cooper to take in some islands to the northward and eastward of Formosa on her way to the same port, and the Hancock to serch for the Porpoise in the Formosa Channel, to survey the southwest and east coast of that island, and then join the other two vessels at the port of destination. From thence we were to proceed by different routes to the port of Hakodadi, island of Jesso, - the Cooper going through the Japan Sea, and the Vincennes and Hancock through a long chain of the islands, touching at Simoda, island of Nipon, and finally joining the Cooper at Hakodadi.
