76 ON RAISING NEW VARIETIES OF THE MIMULUS. 



the blossoms are produced, or whether their blooming will be 

 checked by their being submitted to the lower temperature requi- 

 site for flowering Camellias, &c. &c. I wish also to know whether 

 Moss, Provence, and other summer Roses can be induced to 

 bloom as freely as Noisette, Perpetual, China, Tea-scented, and 

 Isle de Bourbon Roses. Perhaps the kindness of the correspon- 

 dent who replies to these queries, will be further displayed in 

 giving me a few names of the best Roses for foixing. Messrs. 

 Rivers, in their new Catalogue, recommend the Dog Rose, from 

 its easily excitable habit, as the stock on which Roses, for forcing, 

 should be worked : what height should the stock be, to display 

 the flowers to advantage ? 



A few hints on forcing the Persian Lilac, or any other plants 

 calculated to add to the beauty of a conservatory in early spring, 

 would also be very acceptable. 



My last queries respecting conservatory shrubs and climbers, 

 have not been answered : a reply is much wished for, and an early 

 answer to the present is solicited.

 Mimulus. By Calceolaria. 



Though I cannot answer " T. P." and " A Lawyer's Clerk" as 

 satisfactorily as I could wish, yet I can put them in a way of 

 obtaining several varieties of Mimuluses without much expense. 

 Let them get seeds of the different sorts advertised in your last 

 number by Charlwood and Warnbr, and sow each variety as 

 soon now as possible in a seed-pan (which should be about a foot 

 in diameter, and four inches deep, with four or five holes in the 

 bottom). Place the pans in a greenhouse, hotbed, or even warm 

 window in the dwelling-house, and the young plants will soon 

 make their appearance ; give them plenty of air by day, when the 

 weather is tolerable, and early in June prick them out in patches 

 in the flower-garden, where they will flower all the autumn. I 

 adopted this plan last year with two varieties I obtained from 

 Charlwood — variegata and rosea; and though the former were 

 all execrable, the latter amply repaid me, for one small packet of
