These letters include correspondence from the Manchester warehouse, mainly details of quantities and qualities sold, and the despatches to Manchester required to meet them, written by John Bone or John ?Crockwich.
The more significant part of this group, however, consists of several letters concerning foreign trade and merchanting, some from agents in such places as Buenos Aires (James Hodgson, Joseph Green), Savannah (Abraham Stansfield), Calcutta, Condover and Valparaiso, discussing details of sales and barters, ship and cargo insurance, and the state of markets. Highly relevant to this activity are the letters between Daniel Campbell and John Fielden concerning the 1837 cotton crisis which threatened to bankrupt the firm of Wildes Pickersgill, an agency in Liverpool, in which Campbell and the Fieldens were partners (along with George Wildes, John & William Pickersgill and William Bowman); the firm was only saved by John Fielden's successful request to the Bank of England for help, using the assets of Fielden Brothers at Todmorden to gain an advance of £50,000. The drafts of this correspondence are included, as are details of the assets and liabilities of the firm in 1838 and 1842.
Also included are several printed sheets, such as the announcement of the partnership with George Wildes in 1835, several Liverpool cotton market reports from 1837 & 1842, and a newspaper report about the crisis.
