Mr. Seward to Mr. Harris.

No. 20.]

Sir: Your despatch of June 7 (No. 21) has been received.

It affords the President sincere pleasure to know that the government of the Tycoon has exerted so much diligence to bring the assassins of Mr. Heusken to punishment, and that you are satisfied that those exertions have been made with good faith. It is expected that the government will not abate its efforts until the end so important to a good understanding between the two countries shall have been attained.

The punishment of the delinquent Yakonines, who were in attendance on the deceased when the crime was committed, is regarded by this government with high approbation.

I am, sir, your obedient servant,

WILLIAM H. SEWARD.

Townsend Harris, Esq., &c., &c., &c., Yedo.
