the sap has ceased, turn out the tubers 

 from the pots, and having carefully re- 

 moved the soil, put the tubers in flower 

 pans upon a shelf in a dry room. About 

 the beginning of September they pro- 

 duce their new stems; let them remain 

 until they have lengthened from twelve 

 to fifteen inches. Having well drained 

 a No. 12 pot, fill it up with the compost 

 to within four inches of the top, then 

 place the tuber in the centre of the pot, 

 and coil the stem or stems around, care- 

 fully filling up with the compost until 

 about two inches of the stem are left 

 above the soil. After potting, place the 

 pots on a stage out of doors, there to 

 remain till the middle of October, they 

 are then removed to the front of a cool 

 green-house, exposed to as much light

 respect to watering, keep them rather 

 moist than otherwise: when out of doors 

 they are freely exposed to rain. The 



It is from these plants the best cuttings 

 are obtained in the spring. In the fol- 

 lowing May, turn the whole ball out of 

 the pot, in a warm situation in the open 

 ground. After they have finished their 

 growth, take them up and sift the ball 

 through a fine sieve, carefully picking 

 out the tubers. They are then treated 

 in all respects as the older tubers, and 

 will make fine flowering plants the fol- 

 lowing spring. The seeds before sow- 

 ing should be soaked in milk and water 

 twenty-four hours, and the outer shell 

 carefully removed ; they will under this 

 treatment grow much sooner and with 

 greater certainty. They should remain 

 in the seed pot until after they have 

 formed a tuber. A small stick can be 

 placed against each plant, to which it 

 will climb, and it serves to indicate the 

 place of the tuber when the stem is 

 dead. Many seeds will remain twelve 

 months before vegetating." — Card.
