The manufacturing side was under the control of Arthur Dobson, a red-faced man who had been with the firm for twenty years. He very wisely maintained its tradition of the very highest quality coupled with the very highest prices. "Perfect Purity." It was an admitted fact that Pentlove, Postlethwaite and Sharper actually used limes in the manufacture of lime juice. Another startling innovation was the use of calves' feet in the preparation of calf's-foot jelly. This was the more extravagant because, of course, only the front feet of the calf may be used for this purpose. Three back feet make one back-yard. Naturally the price was ruinous. But it all added to the reputation of the firm. And the best hotels thought it worth while to advertise that the pickles and preserves they provided were by Messrs. Pentlove, Postlethwaite and Sharper. It may be as well to add that Arthur Dobson was a knave. When he was talking to Cain he always slated Sharper. When he was talking to Sharper he always slated Cain. His specialty was the continuous discovery of some cheaper place in which to lunch. He would ask Luke Sharper to join him in these perilous adventures, but Luke, in his sunny way, always refused. "Standoffish," said Dobson. "Damn standoffish." Luke Sharper represented the literary side of the business. He wrote all the advertisements. It was a rule of the firm that the advertisements should be scholarly, and that none should appear which did not contain at least one quotation from a classical language. Luke had also initiated the production of various booklets dealing with the materials and the methods of business. Nominally they were published; practically they were given away to any considerable purchaser. Some of these were written by Sharper himself. There was, for example, "The Romance of the Raspberry," of which the _Dilborough Gazette_ had said: "An elegant little brochure." This was a great triumph. Even Diggle had to admit it. He had gone so far as to say that one of these fine days he would really have to think about making Sharper a partner. Other of the booklets were written in collaboration. For instance, in the composition of "Thoughts on Purity," Sharper had the assistance of the Reverend Noel Atall. Luke kept a set of these booklets, bound in lilac morocco, in his room at the office. He loved them. He was proud of them. He regarded them as his children, and would sit for hours patting them gently. As the issue of each booklet was limited to one hundred copies, and it was customary to present one of them with each order of L20 or upwards, some of them were out of print, and difficult to obtain. This had been enough to start the collectors. In book catalogues there would sometimes appear a complete set of the Pentlove, Postlethwaite and Sharper booklets. And the price asked was gratifying. Luke fainted with joy the first time he saw this in the catalogue.
