His Excellency，President Sun Yat Sen，Nanking.
Sir，
I have for a number of years served the Chinese Telegraph Administration as Chief Superintendent & Foreign Adviser & in this capacity concluded important connections with the four foreign Cable Companies and the five foreign powers having limitroph connections with China.I have also personally trained more than one hundred young Chinese for high positions in the Telegraph service.In 1908 I represented China at the International Telegraph Convention at Lisbon.—When the present national rising took place and the head office of the Telegraph Administration was occupied I offered to remain in my office & to the best of my ability assist in all telegraph matters relating to the foreign interests of China， but the young man，who was put in charge， demanded that I should sign a new agreement etc.My agreement is that as my agreement is made with the Imperial Government of China， it is impossible for me to sign any new agreement as long as that government exists， but it does not prevent me from continuing to work for the interest of China as a neutral person.At my return from Peking， I was， however， informed by Mr.Y.C.Fang that I could not again occupy my usual office， because I had refused to sign a new contract.—The Telegraphs of China， require very careful handling as 58,000 pounds Sterling will have to be paid yearly until 1930 and the many existing international conventions will have to be most careful watched and carried out.I appeal to your Excellency to have my office handed back and to allowed as hitherto to watch the foreign interests of the Chinese Telegraph as this is not a political but an international question.
I have the honor to be，Sir，Your most obedient Servant，
T.N.Dusing

致孙逸仙总统，南京。
先生：
我在中国电报局做了多年的主管与外籍顾问，与四家主要外籍电报公司有密切联系。五家能源公司与中国有业务联系。我还在电报业务上训练过上百名年轻人到高级岗位。1908年我代表中国出席了在里斯本召开的国际电报大会。当前全国起义爆发后，电报局总部被占，我仍留守岗位，尽量帮助中国的对外联络。
但被委派负责的年轻人要求我和新政府签订新的合同。我的合同是与清政府签订的，对我而言只要那个政府还存在，我就不可能签订新的合同。但这不会妨害我作为一个中立者继续为中国的利益服务。然而，我从北京返回后，杨先生通知我，我不能再使用我平时的办公室，因我拒绝签订新合同。中国的电报，需要非常小心地处理，每年必须支付58000英镑，直到1930年。许多现有的国际公约需要仔细考察并执行。我呼吁阁下归还我的办公室，并从此保护中国电报局里外国人的利益。因为这不是一项政治问题，而是国际问题。
