"This shall Inform Bassanio that I'm done Brown, My chance is up, my ship, alas! gone down. The vessel on her homeward way, sir, Laden with the rich products of the Fraser (river)-- The famed sal-lals for making jams, Monster sturgeon, cranberries and clams-- Bumped on the sands and so a wreck became; Captain, as usual, 'not at all to blame.' The people here say just as they like, And lay the blame on 'Titcombe' or on 'Pike.' For me, no sympathy I get; to them 'tis fun; Alas for me, I'm 'Capitally' done; Then those brick stores, which I fondly thought For bonded warehouses would soon be sought; Bring 'Nary red,' no revenue they raise; No ships arriving, no one duty pays; From Sorrow's page I've learned all man can know, For 'Cochrane's' just sold off my grand pi-an-o; So if with means to aid me you're invested, Haste, for the Jews won't rest till I'm arrested.
