（前文より続く）…見分を行い、総州（上総・下総）百首へ渡って見分を行い、海岸沿いに房州（安房国）洲之崎へ罷り越し、そこから相州（相模国）三崎町へ渡り、城ヶ島ならびにその辺りを巡見し、海岸沿いを通って出崎の様子等を委細見分の上、一同帰府した。巡見先での見分の次第を逐一申し上げるにあたり、台場を取り建てるべき箇所をはじめ、居小屋敷地、その他に御備場を増設するのが然るべき場所等の見込みの次第を承りたい旨、十兵衛殿が申されたところ、（成瀬幾右衛門は）帰府して主人（越中守様）へ申し聞かせた上でなければ、確答を申し述べることは難しいと断ったところ、追って御両家でよくお打ち合わせの上でご進達なさるべき事ではあるが、まずご自分方のお見込み・ご了見の次第を承りたい旨を申されたので、場所々々の見込み・存寄（意見）の品々を幾右衛門へ打ち合わせ、それぞれ申し立てた。
江戸海（江戸湾）入口の御備方（防衛整備）の儀については、寛政の初め頃に越中守様が御老中御勤役中にお取り調べになり、四、五年以来、浦賀奉行の岩本石見守殿、御鉄炮方の井上左太夫殿が一同、度々見分をお命じられ、台場の見立ても済み、御備筋の荒増（おおよその方針）がお取り調べとなっていた由のところ、今度御両家へ永久のご引き受けとしてお命じになった段は、深きお含み（お考え）のある御事である由、内密に聞き及んでいる。右の通り、越中守様においては御役中よりのお調べの儀であり、悉く御手覚（記録・把握）もなされており、直々に細々とご見分…

(Continued from previous text)…Having completed their survey, the group crossed over to Hyakushu in Sōshū (Kazusa/Shimōsa Provinces) for further inspection, then proceeded along the coastline to Susunosaki in Bōshū (Awa Province), from there crossing over to Misakichō in Sōshū (Sagami Province), conducting a circuit inspection of Jōgashima island and its surrounding areas, examining the coastline and the situation at Desaki in detail. After completing the survey, the entire party returned to Edo. Upon reporting the details of the survey at each location one by one, Lord Jūhei requested to hear the assessment regarding: the sites suitable for the construction of gun batteries (daiba), the plots for temporary lodging quarters, and any other locations where it would be appropriate to increase defensive positions. In response, Ikuemon indicated it would be difficult to give a definitive answer without first returning to Edo and reporting to his lord (Lord Etchu-no-kami). When pressed that, although it was a matter to be formally communicated after thorough discussion between the two houses, he was asked to share his own personal assessment and views for the time being, Ikuemon consulted with the various observations and opinions regarding each location, and presented them accordingly.
Regarding the matter of defense arrangements (o-sonae-kata) at the entrance to Edo Bay, it is understood that at the beginning of the Kansei era, when Lord Etchu-no-kami was serving as a Senior Councilor (Rōjū), he had conducted investigations into the matter. Over the past four to five years, Uraga Magistrate Lord Iwamoto Iwami-no-kami and Artillery Officer Lord Inoue Sadayū had been repeatedly ordered to conduct surveys, completing the assessment of sites for gun battery emplacements and broadly establishing a defensive plan. It is understood through confidential channels that the decision this time to entrust both houses with this responsibility on a permanent basis reflects deep and considered intentions [on the part of the bakufu]. As described above, Lord Etchu-no-kami has been overseeing this matter since his tenure in office, retaining thorough personal records and knowledge of it all, and is personally conducting detailed inspections…
