Dr.Sun Wen，Peking， China.
My dear Doctor，
Sometimes ago I have written a letter to you relating to the matter of financing railways in the south.Upon hearing a few days ago that you are given authority by the national council to shape the railway policy of the country， I again wish to take up the matter with you with a view to arriving at some definite conclusion.
At present， my plans for a bank， doing a volume of business as large as that of the Hongkong and Shanghai Banking Corporation， are about to be carried into effect.The funds for the establishment of this bank is from a loan from American capitalists who have faith in me to handle the funds for the development of railways and industries that will repay the loan within a period of time agreed upon between them and me.
You will be interested to know perhaps that the former governor general of Kwang Tung.Mr.Chan Kwing Ming (前都督陈炯明）has approached me with the proposition of furnishing funds for the Wai Shiw Railway (惠潮铁路）that is now in the course of organization， negotiations between the two sides are favourable and no long the preliminary agreement will be signed.The Macao Canton Railway Co.is also giving consideration to my proposition of financing the road.
In developing the railway lines of the south， three factors are indispensable， first the appointment of a director general， second the securing of funds， and third the organizing of railway companies for undertaking the work of construction.I myself has always thought of taking an active part in this railway development.I therefore wish to ask for any one of the above privilege that you wish to assign me.Concerning the second privilege my bank is ready at any time to furnish the funds.If you think you can get the funds， then may I not be given the work of organizing railway companies or the office of Director General of the Kwang Si， Kwang Tung， Yunan， Szechuan and Fukien Provinces? Hoping to hear from you soon about this matter.
I am，Yours Sincerely，
程天斗

致孙文博士，中国北京。
尊敬的博士：
前些天我写了一封信给您，涉及融资南方铁路的事。听说前几天您被国务院授权，规划我国的铁路政策，我再和您商讨此事，以就此事得到一些明确的结论。
目前，我的银行计划，业务量将会如香港上海汇丰银行一样大，正要实施运行。设立银行的资金是来自美国资本家的贷款，他们对我处理铁路与实业资金有信心，将在一段期限内按照我和他们之间的约定偿还贷款。
或许你会有兴趣知道，前都督陈炯明已就投资惠广铁路的提议和我接触。现正处于组织过程中，双方的谈判很顺利，前期协定不久将会签署。广澳铁路公司也在考虑我投资铁路的提议。
在发展南方铁路路线的过程中，三个要素缺一不可，一是任命一位总经理，二是资金的保障，三是组织铁路公司承担建设工作。我一直希望自己能积极参与铁路发展。所以我想问，您能否考虑优先委派我以上任何一项？关于第二项，我的银行随时准备提供资金。如果您认为自己能够得到资金，我能否负责组织铁路公司，或担任广西、广东、云南、四川及福建省总经理的职位？希望能尽快收到您的来信。
程天斗 谨呈
