VIOLETS FORCING. To obtain Neapo- 

 litan T r iolets in whiter, select a warm, 

 sheltered corner ; cast out trenches a 

 foot deep and five feet wide into the 

 alleys, and make a turf wall all round 

 to the desired height, for holding about 

 fifteen or eighteen inches of leaves, 

 rubbish-heap refuse, or any fermenting 

 materials likely to afford a little bottom- 

 heat, upon which place about eight or 

 nine inches of rich, open soil. The 

 width regulate by any lights to be 

 spared for a time, or thatched hurdles, 

 or other protectors. The plants take 

 up from the store plantation carefully, 

 with balls of earth to their roots, and 

 plant from ten to twelve inches apart 

 each way, first clearing them of any 

 side-shoots or suckers ; afterwards keep 

 clear of dead leaves, etc., well surface- 

 stir, and never allow to get dry. No 

 lights or protection are to be placed 

 over them until frosty nights set in, or 

 very heavy rains; then, at all times, 

 tilt on both sides, with abundance of 

 air, if the weather is not too severe. 

 By such treatment the foliage is always 

 large, thick, and of a beautiful dark 

 green, the flowers abundant, and large. 

 No side-runners are to be allowed to 

 run until April, at which time they are 

 to be encouraged to grow ; and open, 

 sandy, rich soil sifted amongst them, 

 and kept well watered, to encourage 

 them to root freely. A partially-shaded 

 piece of good ground is then to be 

 chosen in the month of May, and the 

 Violets then forked up, old and young 

 altogether, and the best of the young 

 plants selected and planted out, a foot 

 apart each way, singly. They are to 

 be kept well surface-stirred all the 

 summer, and by October they will be 

 fine plants to take up as above described. 

 Russian Violets Single White, Double 

 White, Double Blue, and other hardy 

 varieties grow in a similar way, with 

 regard to planting out the young run- 

 ners and summer treatment, and they 

 are also to be carefully taken up in 

 October ; some placed in turf-pits, with 

 gentle bottom-heat, and some without 

 bottom-heat, and a quantity planted on 



sloping banks. By this simple con- 

 trivance abundance of luxuriant flowers 

 are kept in succession from September 

 till May. Every variety is kept clear 

 from side-shoots or runners all the 

 summer. All the varieties are parti- 

 cularly fond of charred articles mixed 

 with the soil.
