His friendship for Borrow was a great factor in Borrow's life in Russia and elsewhere.
If Borrow's letters to Hasfeld should ever turn up, they will prove the best that he wrote.

Hasfeld's letters to Borrow were preserved by him.
Three of them are in my possession.

Others were secured by Dr.Knapp, who made far too little use of them.

They are all written in Danish on foreign notepaper: flowery, grandiloquent productions we may admit, but if we may judge a man by his correspondents, we have a revelation of a more human Borrow than the correspondence with the friends at Earl Street reveals: ST.

PETERSBURG, _6/18 November 1836._ MY DEAR FRIEND,--Much water has run through the Neva since I last wrote to you, my last letter was dated 5/17th April; the last letter I received from you was dated Madrid, 23rd May, and I now see with regret that it is still unanswered; it is, however, a good thing that I have not written as often to you as I have thought about you, for otherwise you would have received a couple of letters daily, because the sun never sets without you, my lean friend, entering into my imagination.
