On March 4, he writes to his brother:—­

“I have nothing new.  Smith continues to annoy me, but I think I have got him in check by a demand for compensation for my services for seven months, for doing that for him in Paris which he was bound to do.  The agreement stipulates that I give my services for ’three months and no longer,’ but, at his earnest solicitation, I remained seven months longer and was his agent in ‘negotiating the sale of rights,’ which by the articles he was obliged to do; consequently I have a right to compensation, and Mr. E. and others think my claim a valid one.  If it is sustained the tables are completely turned on him, and he is debtor to me to the amount of six or seven hundred dollars.  I have commenced my operations with posts which promise well at present.”

“March 23. My Telegraph labors go on well at present.  The whole matter is now critical, or, as our good father used to say, ’a crisis is at hand.’  I hope for the best while I endeavor to prepare my mind for the worst.  Smith, if he goes forward with his claim, is a ruined man in reputation, but he may sink the Telegraph also in his passion; but, when he returns from the East, where he fortunately is now, we hope through his friends to persuade him to withdraw it, which he may do from fear of the consequences.  As to his claims privately on me, I think I have him in check, but he is a man of consummate art and unprincipled; he will, therefore, doubtless give me trouble.”

“April 10. A brighter day is dawning upon me.  I send you the Intelligencer of to-day, in which you will see that the Telegraph is successfully under way.  Through six miles the experiment has been most gratifying.  In a few days I hope to advise you of more respecting it.  I have preferred reserve until I could state something positive.  I have my posts set to Beltsville, twelve miles, and you will see by the Intelligencer that I am prepared to go directly on to Baltimore and hope to reach there by the middle of May.”

“May 7. Let me know when Susan and the two Charles arrive [his son and his grandson] for, if they come within the next fortnight, I think I can contrive to run on and pay a visit of two or three days, unless my marplot Smith should prevent again, as he is likely to do if he comes on here.  As yet there is no settlement of that matter, and he seems determined (inter nos) to be as ugly as he can and defeat all application for an appropriation if I am to have the management of it.  He chafes like a wild boar, but, when he finds that he can effect nothing by such a temper, self-interest may soften him into terms.

“You will see by the papers that the Telegraph is in successful operation for twenty-two miles, to the Junction of the Annapolis road with the Baltimore and Washington road.  The nomination of Mr. Frelinghuysen as Vice-President was written, sent on, and the receipt acknowledged back in two minutes and one second, a distance of forty-four miles.  The news was spread all over Washington one hour and four minutes before the cars containing the news by express arrived.  In about a fortnight I hope to be in Baltimore, and a communication will be established between the two cities.  Good-bye.  I am almost asleep from exhaustion, so excuse abrupt closing.”
