Dr.Sun Yat Sen， Prov.President，Shanghai， China
Sir：
Permit me to herewith make application for a position under the new Government of China as Chief of Wireless Telegraphs.
This art will prove of immense value in opening up many of the more remote sections of your vast Republic and it will prove of great practical value if you manufacture and develop your own system thus not being in any way dependent on outside manufacturers for new apparatus or renewals.
My proposition would be to meet an Agent of your American Representative and go over the ground thoroughly with him， in the event of the interview being to his satisfaction I would go to China， take any oath of fealty that you would prescribe and start the manufacture of your own system of wireless telegraph apparatus.
For nine years past I have been the technical head of the largest American Company engaged in this line of business and and fully competent to fill the position.
With great respect
Clifford D.Balcock

致临时大总统孙逸仙博士，中国上海。
先生：
请允许我在此申请中国新政府在无线电报业务负责人的职位。
这项技艺在开发你们辽阔共和国的许多偏远地区方面，具有巨大价值。如果你们能够制造和开发自己的系统，毋须以任何方式依赖于外部厂商获取新设备或更新，将更具重大实用价值。
我的建议是，主动与你们的美方代表的代理人碰面，仔细与他一起进行实地考察。倘若面试令他满意，我会去中国，提供你们需要的任何技艺，启动研制你们自己的无线电报系统。
过去9年，我一直是从事这项业务的美国最大公司的技术负责人，完全胜任填补这一职位空缺。
致礼
克利福德·柏科克
