Gentlemen March 28. 1851
Your letter is received. I have made the arrangement to use the Hoyt evidence  in the other cases.
The new Act of Congress provides that all cases begun here shallPage 104 be tried here, & not go to Chicago at all. All our Patent cases were begun here.
It also fixes the summer term here in July,  instead of June as heretofore. So no trouble is created in our Patent cases by the new law. In haste Yours as ever A. LINCOLN
