Seokdo on Imperial Edict 41 ,22Oct1900 is not Takeshima Liancourt Rocks.

Actually there are no map or no records which island be Seokdo on Imperial Edict no.41 on 22Oct1900.

So there are only Hypothesis options now. In the future if there are new record find, we would know which island be Seokdo. Now we have only two records which describes Seokdo. But one denies Seokdo is Liacnourt Rocks.

In this document, it is impossible to judge which island is Seokdo.

2..Hwasong Simbun, Ullengdo administlative area. 13Jul1906

統 監府에서 內部에 公函하되 江原道 三陟郡 管下에 所在 鬱陵島에 所属島嶼와 郡廳設始 年月을 示明하라는 故로 答函하되、光武二年五月二十日에 鬱陵島監으로 設始 하였다가 光武四年十月二十五日에 政府會議를 經由하야 郡守를 配置하니 郡廳은 台霞洞에 在하고 該郡所管島는 竹島石島오、東西가 六十里오 南北이 四十里니, 合 二百餘里라고 하였다더라.

They said Ulleungdo's district is 60ri east-west and 40ri south-nowth and circumstances 200ri. So Liacnourt rocks are out of Ullengdo districtand it can be concluded that Seokdo isn't Liacnorut rocks.

Hypothesis 1 The Seokdo 石島＝竹嶼Boussole Rock

Both Japan and Korean impeiral's recognization, the most prominent adjunctive islands of Ulluengdo is Jukdo-Boussole Rock in various records and Maps, by inspector's.

Checking the original document of Imperial Edict no.41(大韓勅令41）, there are no blank or period between Jukdo(

竹島/嶼）and Seokdo（石島）. Those cases, it can also be possible to read it is "Jukdo other name Seokdo", which suggests one island twin names. Korean scholor insist "it is Jukdo and Seokdo", but it is not confirmed explanation.

Most prominent adjuncive island of Ulleungdo by Korean's recognization is Usando-Jukdo and Most prominent adjuncive island of Ulleungdo is Boussole Rock-Tessemi island. Check the details about "What is "Usando-Jukdo on Hwason Simbum (newspaper)

Also, checking hidrographic magazines both Europe and Japan, Boussole Rock-Jukdo（竹嶼） had been explained most prominent adjunctive island of Ulluengdo. although, Liancourt rocks is independently explaind from Dagelet-Matsushima-Ulleungdo. So it can be a choice which Seokdo be Jukdo-Boussole Rock.

Jukdo was biggest adjunctive island of Ullengdo by Japanese recognization.

水路雑誌

鬱陵島（一名松島）・・・省略・・・竹嶼（朝鮮人之を竹島と云う）を除くの外一岩嶼の岸より二鏈牟を出る者なし。竹嶼は此島の近海にて最大にして島の東海岸を距 る。七鏈竹嶼の北方約五鏈に一嶼あり。北方に向て洞穴二個並列す。

hidrographic magazine

Ulleungdo(a.k.a Matsushima).......(omit).....except Jukdo竹嶼(which Koran call it Jukdo竹島) there are no rocks out of Ulleungdo 2?? and Jukdo is most biggest nearby Ulleungdo in the east of Ulluengdo. North of Jukdo, there are a island with two caves on north.

鬱陵島（一名松島）海軍海図第五四号第九五号を見よ・・・中略・・・何れも鬱陵島の如く走界にして錘測も恃みとするに足をす然 れも竹嶋（此嶼は島の東濱を距る七鏈の處にあり）を除くの外、皆本島の崖岸を距る1/4里以上に出る者なし。島の北濱に接して孔岩あり岩を貫きて一大孔あ るを以て其形甚奇なり此岩と相對せる陸岸に高さ大凡八〇〇呎の花崗岩山あり滑面禿兀峻険にして形糖塔の如し。

Hypothesis 2

Seokdo is South Five Rocks, which is part of "Six small adjunctive rocks of Ulleungdo incruding most prominent of Usando(Jukdo). This five south islands were described till 1900 altough it is ghost island.

（Mainly Gerry Bevers insist it）

In the DaedongJisi(大東地誌) written by Kim Jonho金正浩 in 1864, he explains Usan is another name of Ullengdo, quoted from the recognization of Yeojisunram輿地勝覧 so he omitted Usando-Jukdo.But he draw there are five island on south of Ullengdo, same like typical Korean Detailed Ulleungdo maps after 1694 so it can assumed that Korean believe there are "Five South Island". those unknown island, it is some possibility that they named "Seokdo" is catch-all easy name on it.
