ROSES AT THE PANAMA-PACIFIC EXHIBITION
"Messrs. Hugh Dickson, Ltd., Royal Nurseries, Belfast, have received official intimation that they have been awarded the $1000 Trophy at the Panama Exhibition, for the best New Rose not yet in commerce. This unique International Award has been won under the most strenuous competition and after the most searching trial ever conducted at an international exhibition. The Exhibition authorities invited all the Rose Hybridists of the world to send for trial the best of their seedlings, the plants to be planted in a specially prepared garden in the Exhibition grounds, and there grown for a year before the Exhibition opened, so that they would be thoroughly acclimatised and established before the test of judges was undertaken. The response was world-wide, and we are informed that practically every country in the world was represented by the best products of their hybridists. The method of judging was most exacting, each variety - grown under number only - was judged every month of the period of the Exhibition by a group of the leading Rose growers of America, who awarded points to every rose competing, each set of judges being different on each occasion. At the end of the test the total points were counted, with the result of a brilliant success for our Belfast firm, who are to be heartily congratulated. The Governors of the Exhibition reserve the right to name the new Rose*, and Messrs. Dickson and Rosarians generally will await, with what patience they can, the name this famous rose is to bear." - Belfast News Letter.

* The Rose has since received the name of "California."
