The pursuits connected with book-making were not, however, without their trials and troubles, even at that early day. From some of Hancock's letters for the year 1736, we find that one Cox was a sad thorn in his side, a grievous lion in his daily path. His chief correspondent among the booksellers in London at this period was Mr. Thomas Longman,--the founder of the renowned house of Longmans of our own time,--and to him Hancock often pours out his trials and grievances in the quaint and pointed style of the business letters of "The Spectator's" own day. Under date of April 10, 1736, for instance, he writes,--"I cannot Think of Doing much more in the Book way at present, unless Cox Recalls his Agent, which I am Certain He never will if you give up this point," (_i. e._ of making larger consignments to Hancock on his own account,) "as I can Improve my Money In other Goods from Great Brittan to so much better Advantage." Yet, he continues, "I am unwilling Quite to Quit The Book branch of Trade, and you Can't but be Senceable that it was my Regard to you has Occasioned it's being forced from me in this way." About the month of May, 1738, Cox appears to have become wellnigh intolerable. On the 24th of that month our bookseller writes to Longman,--"Cox has Sent some more Books here this Spring, & I Cannot Learn that he's Called his man home Yet. I am a Great Sufferer by him, as well as you, having above £250 Sterling in Books by me, before what Came from you now." Sometimes, however, Cox makes a slight mistake, and then our bookseller again takes heart of courage. Thus, under date of October 29, 1739, he again writes to Longman,--"Cox's man Caine in Hall's ship about a month Agoe, brought Eight Trunks and a Box or two of Books, has opened his Shop, but makes no Great Figure & is but little taken Notice off, _which is a a Good Symtom of a bad Sortment_,--his Return here was Surprising to me; truly I did not Expect it. At present I don't know how to Govern myself as to the Book Trade, _but am willing to do the Needful to Discountenance him_, and will write you again in little Time." But, alas! by the 10th of December following, Cox had rallied bravely, and, accordingly, Hancock again writes in despair,--"I know not how to Conduct my Affairs as to the Book Trade. Cox's Shop is opened, & he has a pretty Good Collection of Books. He brought with him 8 Trunks, & 4 Came in y'e next Ship. His Coming is A Great Damage to me, having many Books by me unsold for Years past, & most all which I had of you this Year. I am Ready Sometimes to Give up that part of my Business, & I think I should have done it ere now, were I not in hopes of Serving you in that Branch of Trade. _Could you propose any Scheem to discountenance our Common Enemy I will Gladly Joyn you_. I fear he will have more Goods in the Next Ship. I have Nothing to Add at this time only that I am with Great Esteem Your Assur'd Fr'd &c. T. H."
