the whole situation, must have a capacity 

 to supply heat for at least 1,250 feet of 

 radiation, or the boiler must have about 

 160 square feet of heating surface, which 

 means the area of the surfaces exposed 

 to the fire and heated gases. 



The piping will be as follows: House 

 18x48 feet piped with l^^-inch pipe re- 

 quires 620 feet and with 2-inch pipe 

 496 feet. The house 16x100 feet piped 

 with 1%-inch pipe requires 1,154 feet and 

 with 2-inch pipe 923 feet. The house 

 15x45 feet piped with l^^-inch pipe re- 

 quires 480 feet and with 2-inch pipe 384 

 feet. Or ten runs of 2-inch pipe in the 

 house 18x48 feet, nine runs of 2-ineh pipe 

 in the house 16x100 feet and nine runs 

 of 2-inch pipe in the house 16x45 feet.

FORaNG LILAC IN FRANCE. 



M. Jules Veran, a French writer, gives 

 some' interesting facts about forcing li- 

 lac, as follows: 



"The lilacs to be forced are repottcl 

 at the end of June or the beginning of 

 July, according as the weather is more 

 or less sunny. Care is taken for the fir.st 

 fortnight to keep the plants in a shady 

 place, where they are constantly kept 

 covered; they must never be allowed to 

 wilt; for this reason they are only re- 

 potted early in the morning or in the 

 evening, the pots being plunged up to the 

 rim. Watering is done frequently, and 

 once a week liquid manure well dilute! 

 with water is applied. Watering is re- 

 duced in amount toward the end of Sep- 

 tember and the beginning of October, 

 when the leaves begin to fall. At this 

 season the pots are dug up and placed 

 «ide by side, watering being altogether 

 stopped, so that the plants may enter 

 upon a period of rest, when excess nf 

 moisture would cause rotting of the roots 

 Trithin the pot. For this reason the 

 plants are, from November onward, kept 



under shelter from the autumn rains. 

 This condition, modified according to cir- 

 cumstances, is an important essential for 

 forced lilacs. The plants should also be 

 covered with a deep mulch of dry ma- 

 nure. 



"Forcing begins about the middle of 

 November, in order that the flowers may 

 be produced for Christmas or New 

 Year's. The forcing house is divided 

 into three compartments ; one is com- 

 pletely covered over to exclude the light, 

 the plants being placed side by side, the 

 stems only being wetted with warm water 

 at a temperature of 28 to 30 degrees 

 Reaumur (say, 95 to 100 degrees Fahr.), 

 In three weeks ' time the, flowers expand, 

 and it is then necessary to e:q)ose them 

 to the light. They are in consequence 

 removed to the secopd compartment and 

 well .Watered. After* week the' flowers 

 begin to show color, 'When the plants are 

 removed to the third compartment at a 

 temperature of 15 degrees Reaumur (66 

 degrees Fahr,), where the flowers assume 

 their normal color. 



' ' This plan demands five or siit weeks ' 

 longer time than is required when the 

 plants are subjected to complete darl;- 

 ness,' but the results are stated to bo 

 superior. After New "Year/s no more 

 plants are placed in the dark, but they 

 are copiously watered. Forcing termi- 

 nates at the end of April. The shrubs 

 that • have not been forced, as well as 

 those from which the flowers have been 

 removed, are cut down and planted in 

 the open air, when in two years' time 

 they are ready to be again potted and 

 subjected to forcing."

 planning to build two good-sized green- 

 houses to accommodate the needs of his 

 increasing trade. H« has had a small

DENDROBIUM PHALAENOPSIS. 



Apart from their merits as useful 

 plants for house decoration and for 

 cutting purposes generally, the numerous 

 distinct varieties of this beautiful spe- 

 cies are among the finest of exhibition 

 plants, especially as the flowers remain 

 fresh on the plants for a very long time, 

 and also when cut. The plants of D. 

 Phalseno^sis will soon make nunierous 

 young roots from the base of the new 

 growths. Before these have made much 

 progress, any plants that need more root- 

 room should be repotted^ when tJiia roots 

 will quickly establish tbemselvetf.tn the 

 fresh compost. Where it is inteaded to 

 hang the plants up to the roof, small 

 shallow pans are generally preferred; 

 but the ordinary flower-pot with wire han- 

 dles attached may also be employed. 

 Whichever be used plenty of drainage 

 is necessaryi' I am using paJ^B for the 

 smallest plants, and providing only a 

 thin layer of fibrous peat and 3phagnum 

 moss for them to root into. Larger ex- 

 amples are placed in pots with, a com- 

 post of peat, leaf soil, and sphagnum 

 moss in equal parts ; a little coarse silver 

 sand and. a few small crocks are added 

 ...to the compost during. the repotting proc- 

 ess. The pots are ^Ued nearly to the 

 brim ifrith soil, and 'a layer of clean 

 picked moss is packed firmly atound the 

 base' of the plant Thbse plants pro- 

 vided with such a corapost will require 

 very careful watering all through the 

 growing season; it is only necessary to 

 keep the surface moss in 'a fresh grow- 

 ing condition. Those plants in pans 

 with a much smallei" amount of compost 

 will require an abundance of water until 

 the flowering season is past. In either 

 case very little water will be needed for 

 several weeks after repotting, but as the 

 new shoots lengthen and roots become 

 more plentiful, the supply must be grad- 

 ually increased. When in full growth
