Pierre Guillott, and Malmaison, in a house by themselves and keep them grow- 

 ing without intermission until after the holidays. When cold weather sets in 

 they will, of course, require fire heat. The temperature should be kept at from 

 55° to 60° at night. The blooms obtained will pay for the expense of growing. 

 The plants may be potted late in December or early in January, and after 

 being kept a week or two in same temperature to somewhat establish them in 

 pots, may be put away in a very cold house or plunged in frame (taking care 

 that severe frost does not injure the roots) until spring. With this treatment 

 they will make fine plants for late spring sales. If fine specimens are desired 

 do not place the pots close together, but allow a space of at least one inch, SO' 

 that the air may have access, causing the plants to swell their lower buds and 

 become furnished with foliage from the rim of the pot upwards. If crowded, 

 they will break only towards the top, the lower branches remainiog bare. 



When brought into the house they will require more room as growth ad- 

 vances. Those grown out doors should be lifted and potted, in this latitude, 

 from first to middle of November, or as soon as slight frost has checked the 

 growth; in lifting great care should be taken to keep the roots from getting 

 dry, and the plants should, when potted, be shaded for a week or two to keep 

 the wood fresh and plump. The first crop for selling is usually not wanted 

 before Easter and should be brought in from cold frame seven to nine weeks 

 previous to that time. After bringing in, the temperature should, for the first 

 three weeks, not exceed 40° at night, and may be gradually increased to 55°. 

 Other lots may be brought in at intervals to keep up a succession. A critical 

 period occurs when firing for the season is discontinued; mildew is then to be 

 guarded against; many houses are ruined by it at this time. An effectual 

 remedy is made by boiling five pounds tobacco stems and ten pounds flour of 

 sulphur in thirty gallons water until it is reduced to ten gallons. Apply this 

 mixture with syringe in the proportion of one pint to two gallons water. Use 

 of it as a preventive should be commenced before firing is stopped. While 

 firing, the occasional sprinkling of the heating pipes with sulphur, and caution 

 against exposure to cold drafts, will be sufficient. Syringe with diluted fir-tree 

 oil (or, better still, dipping the plants) is an effectual remedy for red spider; if, 

 however, syringing with water be regularly attended to, there is not much dan- 

 ger from the pest. An occasional watering with weak guano or manure water 

 after the plants have set buds will improve the blooms. Before taking the 

 plants to market, it is well to tie the blooms in tissue paper to prevent injury 

 from jolting on the journey. If the buds (particularly of the teas) are tied in 

 stiff paper, leaving one end open when they first show color, they will attain 

 greater size. 



Among the very best hybrids to grow are Gen. Jacqueminot, Magna Charta, 

 Paul Neyron, Merveille de Lyons, Baroness de Rothschild, John Hopper, Anna 

 de Diesbach, Madame Masson, Queen of Queens, Paeonia, and Duchessede Mor- 

 ny ; the last two varieties do not produce particularly fine flowers, but they 

 are of such good habit and freedom of bloom as to merit growing in large 

 quantities. Of the hybrid teas none are superior to La France, Pierre Guil- 

 lott, Lady Mary Fitzwilliams, Antoine Verdier, and Countess of Pembroke. 

 In the teas none are better than Perle des Jardin, Madame Welch, Marie Van 

 Houtte, Etoile de Lyons, Madame de Vatry, Madame Cusin, Coquette de Lyon, 

 and Marie Guillott. The last variety is one of the most profitable ; its flower 

 are pure white and of good substance ; it pays to grow it for flowers in summer 

 alone, and it is the best white tea for pots in spring ; it requires a stony, clayey
