To turn all the plants out in "the first w-eek in 

 May," withi)ut reference to any contingency, should 

 not be done. All pknts should be early inured to 

 the open air — the ventilators and sashes should be 

 kept open as muck as possible, yet by degrees.— 

 Sudden changes of temperature engenders mildew, 

 and a species of consumption fatal to many plants. 

 The hardiest things should be placed out first., m a 

 somewhat shaded spot, and if possible on a bottom 

 of coal ashes, to keep out worms — Azaleas and 

 Khododendrons, Daphnes and Camellias may go 

 out when their growth is finished ; no spot will be 

 too shaded, provided they can get an abundance of 

 air all around. If plants -are well rooted, and have 

 not been repotted, they should be so before setting 

 out, as they will, otherwise, suffer at times for want 

 of water. It is objectionable to turn out every 

 thing, leaving the greenhouse for the season like a 

 lumber loft — such as will stay in advantageously 

 should be left, and the idea is becoming prevalent 

 that Cape and hard wooded thing;s are better in 

 than out. 



Abutilons, Habrothamnuses, and Cestrums, in- 

 deed many similar plants, if taken out of their pots, 

 turned out mto the open border, and lifted and re- 

 potted early in the fall, will make fine growth and 

 do well. As fast as Hyacinths in pots are done 

 flowering, turn them out into beds. Calceolarias 

 should be kept in thecoolest part of the house, and 

 have a good supply of watery as they frequently 

 die after flowering, cuttings of desirable kinds should 

 be taken off* now ; if they show signs of flowering 

 before fall, do not allow it. Cinerarias should re- 

 ceive the same attention, as they also die out after 

 flowering. As soon as the Chrysanthemums, plan- 

 ted last month, have shot forth, take cuttings for 

 next season's show; they strike very readily in 

 sandy soil, in a somewhat moist and shady situa- 

 tion. Dahlias need not be put out before the second 

 or third week in May ; they do not like the scorch- 

 ing heat of summer, and if put out early become 

 stunted and do not flower till later. Pelargoniums 

 should have all the light possible till they begin to 

 open their flower-buds, when they should be some- 

 what shaded and kept cool , by this the flowers are 

 rendered finer, and last longer. Everblooming 

 Roses, grown in pots, should be pruned-in a little 

 after their first flowering, kept a little drier tor a 

 week or so, then repotted, and placed where desired 

 out of doors ; they delight in a rich loamy soil, and 

 are benefited by manure water while growing ; those 

 who have not a collection should begin ; there is no 

 finer class ; six of the best for pot culture may be 



Smivenkr de la Mahnaison, salmon white ; Decom- 

 -ensis^ pale lemon ; Hermom^ rose ; Agrippiaa^ 

 crimson ; Ly&nnak^ pink ^ and, as a frec-blooming 

 white, (Ms, 



Justicias, Aphelandras, and Acanthaceous plants 

 which have been the mainspring of beauty in this 

 department most of the winter and spring, and 

 have now done floweriRg, shoiald liave the lightest 

 and driest p&rt of the house, to ripen well their 

 wood, preparatory to being cut back and repotted 

 for next season's flowering. The Achimenes and 

 <jrloxinia will be coming oi3 to take their places ; 

 they like a moist beat circulating among their roots, 

 and do well with muck rough material in the soil. 

 Pent as camea, or similar soft-wooded plants grown 

 for flowering early in the fall, may still be repotted 

 if the pots become filled with roots. As the 

 weather becomes warm, shade tlie house a little to \ 

 keep the sun from scorcbing. We like to see all 

 plants under glass have a slight shade in sunnner 

 time. Water m the morning, keep the syringe go- 

 ing in the evening, keep the temperature regular 

 between C0° and 70°, and all will go well.

To fully discuss this subject we should properly 

 understand the physiology of plants, because the 

 functions of vegetable life are governed by certain 

 principles, as niiich so as in animal life. 



The different parts of a plant have their offices 

 to perform which are essential to their healthy 

 existence. The destruction or derangement of any 

 of those parts deprives them of the ability to perform 

 ttieir duty well for the want of rhose parts, because 

 no part can perform the office of another. If our 

 views be correct, it then follows that if we wish to 

 produce a certain effect it must be done in harmony 

 with the above principles. This cannot be done 

 unless we know what each part of the organism per- 

 forms and what relation it holds to each other, an x 

 the surrounding influences. 



Every seed preserves the principles of life and 

 retains organic matter to nourish the young ph;nt, 

 and when placed in congenial soil germinates. Its ra- 

 dicle attaches itself to the soil, and the germ seeks 

 the atmosphere; the cotyledons are developed and , 

 the elementary plant is established by virtue of in-
