[Advt,] a GIBSON V. GREENWOOD. £ To the Editor op the "Evening Mail.'' Dear Sir. — My attention having been drawn to an ad in your Saturday evening's issue, I am taking the liberty of replying thereto through the medium of your advcr« tising column. In the first place my ad was a challenge to Fancy Skating, and not 1 hurdle jumping, on an independent floor for tbe Bimple reason that Prof. Gibson knows the Palace floor and I the Princess, and although he may say that I have performed on Baigent's Rink, I can Btate at once with Mr Baigent's authority that he can practice there all day long in order to compete with me. 1 would not have issued the challenge but for his " wild assertions " that he taught me all I know. ' Why, Sir, I have forgotten more than he ever learnt, let alone teach me, which I distinctly deny. Again, it is not in my province to assail any pro* f essional but when bombast is put forward to take the place of pure and nimplc superiority, then I think it my place and duty as a professional man to ask him or anyone else to try conclusions with me on the rollers. I do not take an evasive challenge as an answer to mine, and will meet him any night ho likca ou Baigent's floor, and skate him to a finish in Fancy Skating, including two wheel skating and skating with only one skate on. As far as money is concerned I |am awfully obliged to him to give me such odds as £5 to nothing, but I do not want that liberality. I will give £ for £ up to £20 according to my ad, and if he says his agreement with his employer ie such as to preclude him from using any other Rink well then let him ask them to give him the necessary leave to meet me, and not try and shuffle off by an ad which I consider arrant nonsense. I have no doubt some arrange- ment can be made between the proprietors to compensate the one for the business Mr B. may do through the extra attraction. There is a good chance now that Mr Simmons is coming over to get a judge, who I am sure would be an upright one.
