" The first flowering plants are put in the forcing-house the end of January, 

 and will come into flower about the middle of March. When these plants have 

 done flowering, and are removed from the drawing-room, or green-house, I 

 prune out most of the old shoots that have flowered, so that the plants are 

 furnished regularly with young shoots for flowering the ensuing year : these 

 plants are also placed in the forcing-house for ten days, to ripen the young 

 wood and dry up the moisture, and are then put to rest in the green-house as 

 usual : such plants will flower a second time in October; others, put in the 

 forcing-house the middle of February, will flower about the end of April : if 

 then pruned and dried and put to rest as before, they will flower a second time 

 in November, and so on in proportion. I repot them at all seasons whenever the 

 plants may require it, always observing to keep the pots well drained with pot- 

 sherds, that the moisture may pass off" readily. This process may be considered 

 troublesome j but superior growth, and abundance of flowers, amply repay the 

 care bestowed. By the above treatment, the Cereus speciosus and Jenkinsoni 

 have generally produced from ninety to a hundred fine expanded flowers at 

 one year old. The plants that I brought to the Society [May 21. 1833] were 

 about two years old : the C. speciosus bore two hundred flowers, C. speciosis- 

 simus seventy-two, and C Jenkinsom one hundred and ninety-four. I prefer 

 growing them in wooden tubs, with wire stakes fixed to the tub, to the 

 usual mode of supporting them by stakes driven into the ball of the plant, which 

 I consider, injures the fibre, and makes the plant appear unsightly." 



52. Report on some of the more remarkably Hardy Ornamental Plants 

 raised in the Horticidtural Societi/s Garden from Seeds received 

 from Mr. David Douglas, in the Years 1831, 1832, 1833. By. 

 George Bentham, Esq., F.L.S., Secretary. Read Jan. 21. 1834. 

 [It is much to be regretted, that a general abstract of the whole of 

 Mr. Douglas's voyages and travels, some notes of his life, and a 

 list of all the various articles which he introduced, has not been 

 published in one connected narrative. We hope this may yet be 

 accomplished by his early friend and patron, Mr. Sabine. In the 

 mean time, the following article v^'ill be read with intense interest, 

 and it will of itself, we think, justify the exertions that are now 

 making to raise an appropriate monument to the memory of 

 Douglas.] 



" The reasons which induced the Council of the Horticultural Society of 

 London to engage Mr. Douglas to undertake a second expedition to the north- 

 west coast of America, are mentioned in the preface to the 7th volume of the 

 Transactions, where it is also stated that he embarked on the 26th of October, 

 1829. After a prosperous voyage, he safely landed, in the spring of 1830, at 

 the mouth of the Columbia river. 



" Here he met with many difficulties and disappointments as to the journeys 

 he had intended to make to those parts of the interior which pi'omised the best 

 to reward his exertions. The natural obstacles opposed by the wild state of 

 the country were, in many cases, rendered invincible by the dangerous character 

 of the natives ; and the whole season of 1830 was consumed in short excursions 

 in the neighbourhood of the Hudson's Bay Company's Fort. 



" In the winter of 1830-31, an opportunity occurred of communicating with 

 the northern part of Spanish California, of which Mr. Douglas availed himself, 

 and landed early in 1831 at San Francisco, from whence he proceeded to the 

 Spanish settlement of Monterey. At this place he was well received by the 

 monks, and every facility was aflbrded him for exploring the country in the 

 neighbourhood. He remained there the whole summer of 1831, intending to 

 return to the Columbia river, in the autumn of that year, by the vessel which 

 had brought him to Monterey, and which was expected again to touch on that 

 coast. Owing, however, to the death of the captain, the opportunity did not
