dium is formed by adding a s-inch potful of bonemeal to a bushel 

 of loam. 



Starting Tubers into Growth. Tlie tubers of the tender 

 Nymphffias should be started not later than the beginning of April. 

 Each tuber should be put in a s-inch pot, using pure loam. The 

 tuber may be covered with about an inch of soil and a further layer 

 of half an inch of sand, and put in a tank of water at a temperature 

 of from 65 to 70 degrees. After a few leaves have been made the 

 growth should be separated from the tuber and repotted, as this 

 prevents numerous shoots developing when planted out and secures 

 a strong, single growth. This applies to aU of the tender sorts. 

 The tubers may be pushed back in the s-inch pots, where they will 

 continue sending up fresh shoots; these, or as many as wanted, may 

 be pbtted in 4-inch pots and allowed to go to rest in them. Tubers 

 thus formed should be kept for stock purposes, instead of old 

 plants. 



Summer Quarters. In this latitude it is safe to put out the 

 tenderest kinds after the loth of May. Each plant, whether grown 

 in sunken tubs, boxes, or planted in the bottom of the pond, should 

 have at least three bushels of prepared soil to grow them well. One 

 foot beneath the surface is a safe distance; but they will thrive 

 much deeper. 



Starting Hardy Nymphaeas. By the beginning of April any 

 of the hardy Nymphaeas, which it is necessary to increase or replant, 

 should get attention before they make too much headway. In divid- 

 ing up such kinds as N. helvola and the pink varieties of N. odorata 

 with small rhizomes, such as N. odorata rosea and N. exquisita, or 

 the small pieces of N. Marliacea chromatella, it is safest to start the 

 pieces in pots so that they will make a few leaves before being trans- 

 ferred to their permanent quarters. Such kinds as N. alba, N. a. 

 candidissima, N. Marliacea albida, N. M. rosea, and N. M. carnea 

 have very large rhizomes, and there is Mttle danger but that they 

 will give a good account of themselves after being divided and 

 planted out. 



Wintering Tender Water Lilies. From the isth to the end 

 of October the tender Water Lilies should be taken indoors for the 

 Winter. Where there are small plants or tubers of the tender day 

 blooming species and varieties, such as N. zanzibarensis, its varieties 

 as azurea and rosea, the Australian N. giganlea, N. cmrulea and N. 

 capensis, let the old ones go, as they are difficult to keep over the 

 Winter, except in a large greenhouse tank. Small, dormant tubers
