flows iiro used, tlie iiuiiilxT of returns 

 sliould be eleven and ten, respectively. 



One flow pipe should be placed upon 

 each plate, and the other under the 

 ridge, provided three are used. With 

 four or five flows, one might be carried 

 on the purlin posts, or suspended about 

 halfway Ix'tween the ridge and the 

 plates. One coil of returns should be 

 on each side wall, and others may be 

 carried on the sides of the beds or on 

 the purlin i)osts. 



HEATING PROBLEMS. 



1 should like to know what height a 

 brick chimney should be, having a flue 

 33x18 indies. I liave a Thatcher 

 steam boiler, 7-section, with ii grate area 

 of 112.57 stpiare feet. The boiler is 

 rated at '.\,'HH) scpiarc feet. How many 

 coils would be required for a hous(> 

 3(>xS)l* feet, both ends being of glass.' 

 The house is fourteen feet to the ridge. 

 The sides are five and one half feet to 

 the eaves and contain one row of 

 glass, ](ix24 inches, the remainder being 

 wood. A 4-inch main flow ]iipe extends 

 the full length of the house, with \V^- 

 inch returns. The tem|)erature desired 

 is ijli degrees at 10 degrees below zero. 

 A shed ten feet high is the only building 

 near the house. Would this Ijoiler heat 

 a connected house of the same size, witii 

 lU) se|iaration, to the same teniperaturt' .' 



A. S.— R. I. 



A chimney forty feet high would be 

 amj)le and thirty feet above the point 

 where the smoke ''liters would answer, 

 unless a considerable increase is made in 

 the amount of radiation carried. 



In addition to a 4-inch main, we should 

 use twelve IVi-inch returns. If five 

 coils are used, we should place three 

 pipes in each of the outside coils and 

 two in each of the others. A 2Vi;-iiicli 

 o\'erliead flow ]>ii>e would really answer 

 for this house, using steam. The boilei- 

 will rt>adily carry one, or even two addi 

 tioiial houses.

The Market. 



lousiness was exccjit ioiially good last 

 week. Stock was unusually plentitiii 

 and reasonably clieai>, and large (jiiaii 

 titles were moved daily. 



It lias been many years since there 

 has been such an abundance of cut 

 flowers and plants at Easter as was in 

 evidence on every hand this year. .Ml 

 the greenhouses and regular ilealers 

 had l.irgc stocks, several dealers con- 

 ducting tciiiporary stores for the han- 

 dling of their large consigiiinellts. All 

 of the de|»artiiieiit stores oj)ened tem- 

 porary flower booths and all the corner 

 groceries, news stands and other stores 

 handled vast numbers of potted ])lants, 

 ]iriiici]i;illy bultxiiis stock. 



With the excj']ition of Easter lilies, 

 prices were slightly lower than thosr 

 that ]irevailed last year, while, as a 

 rule, the stock was of a better ((Uality. 

 Lilies which last year brought at re- 

 tail ].■), 2n and 25 cents per bud or 

 bloom, this year were (pioted from 25 to 

 39 cents. Potteil bulbous ]il;ints brought 

 an average of 15 ctMits per stalk. 

 Weathi'r conditions were auspicious for 

 lierfect deliveries ."ind huiidreijs of jiots 

 were taken away by the jiurclL-isers. 



When H(dy week opeiiecl with a rec- 

 ord-lire.'iking oflicial temjierature of 83 

 degrees, consteriuition reigned with

Being of a rubbery consistency, SEALRITE 

 remains plastic within while hardening on the 

 outside. It cannot crack or peel. 



SEALRITE is unexcelled when used as a 

 glazing material. Makes all loose panes tight 

 and lengthens the service of cracked panes. 



Prepare for the future now. Ask us about
