Can you recognize the English on the warrant?

from google:
Treasury warrant is an order in the form of a check. It is through treasury warrants that government disbursements are paid. With the treasury warrant, a drawer authorizes someone to pay a particular sum of money to another.

It looks like it was made out to Edoard de Stoeckl, Envoy . . .?

for $1,200,000.

It was paid August 1, 1868.

Geez, Ori - if you would have identified the source of your picture, this would have been a lot easier.

Stoeckl was the diplomat who negotiated the sale of Alaska to the US in 1867. No clue as to why a check would have been made out to him for $1,200,000.

That is 7.2 million USD, PUNKEY, NOT $1,200,000.

The handwriting on the check seems hard to recognize.

Yes, it is a 7.

Still, it would have helped if you had posted the source with your original post.
