 sell them on their merits. 



OIL FOR FUEL. 



A s(ibs.ril)er in New Vork state re- 

 <pu'sts the pul)lication uf the folh)\ving 

 inquiry: 



''Florists wlio have made use of oil in 

 [dace of coal for fuel, please advise us 

 through this column as to the cost and 

 cliaracter of burners, life of same, ettect 

 oil has on boilers, and relative cost of 

 oil and <oa). Have any florists useil 

 peat in place of coal? If so. what is 

 its cost as comparetl with coal, and 

 where is it to ))e found in Xew Vork 

 state?" 



The Keview will be jdeased to give 

 space to any replies. 



OREGON VEGETABLE HOUSES. 



1 a,m going to build two hothouses, 

 each 30x150 feet. The houses will be 

 connected. They will be built on ground 

 that slopes to the east. There is about 

 four feet of a drop in the loO feet. The 

 lioiler will be at the east end of the 

 iiouses. The walls of the houses are six- 

 feet high and the ridge is thirteen feet 

 from the ground. These. houses are for 

 tomatoes and cucwnbers. We want a 

 temperature of 65 degrees at night and 

 70 to 80 degrees in the daytime, at 4 tle- 

 grees below zero. There are four beds 

 <»n the floor, the full length of the house. 

 How many 2-inch flows and returns will 

 1 need and where would you place them 

 to get the best results? Where would 

 you place the expansion tank'? I want to 

 use the gravity system, to help the flow 

 of water. The supply taiik will be above 

 the houses, on the higher giound. What 

 size of feed pipe will 1 nee<l? What 

 size of Imiler? 8. B. H. 



Kach of your houses .iOxl.lONrequires 

 sixteen lines of 2-iiu'h pipe to supply 

 sufficient radiation to maintain the tem- 

 perature desired. It will be advisable to 

 nsii three lines in each house as risers. 

 ;ind the thirteen returns in as nmny coils 

 MS there are risers for each house; tiiat 

 is. two coils of four i)ipes each and one 

 with five. 8uch a jilant will re(|uir<' a 

 noiler with about 400 s(|uare feet of 

 heating surface. Vou can place the ex- 

 pansion tank in any convenient locati()u, 

 provided it is fifteen or twenty feet 

 above the heating |»ipes anil connected 

 with the main return near the ))oiler. 



A CONCRETE SMOKESTACK. 



Th(nigh there is a steady increase in 

 th(> use of cement for certain jiarts of 

 gr(?enhouse constructicui, cement smoke- 

 stacks are probably still rather rare in 

 the trade. The smokestack shown in the 

 illustration looks substantial and work- 

 manlike, and one of the most interesting 

 facts with reference to it is that it was 

 built by the owners themselves, Van Aken 

 Bros., of Ooldwater, Mich., who thus de- 

 scribe the method used in doing the 

 work :

"We commenced with a foundation 

 twelve feet square by nine feet ' deep. 

 This was ma<le solid with cobblestones 

 and cenu'Ut grouting, using a cement 

 mixer and running the grouting thin, so 

 it would fill all hollows between the 

 stones. Six feet down in this we set 1%- 

 inch and l-Vi-inch iron pipes on end, so 

 that they extended upward as reinforce- 

 ment for the stack. Above the founda- 

 tion, where we set our first form for th<' 

 stack, we wired old buggy tires to the 

 j)ipes i'\ery ten inches, thus making a

conqilete and ^e(•ure reinforcement for 

 the stack. Our forms were three feet 

 high and were put together in sections, 

 which wi' fastened in place by wiring 

 them to the iron pipes. We used two sets 

 of the forms, removing the lower set 

 each day. putting it on top and refilling 

 it. Thus we went up three feet per day. 



"Tlie stack has a 3()-inch flue. All 

 scatt'olding was placed inside, thus saving 

 a good deal in that item of ex|)ense. The 

 wall for the first thirty feet is eight 

 inches thick, and the upper thirty-two 

 feet is six inches thick. In the upper 

 thirty-two feet we also reduced the size 

 of the reinforcing pipes to 1-inch. 



' ' The entire cost, including the making 

 of the wooden forms and the excavating 

 for the foundation, was $290. The con- 

 'nection to the boiler is made with a ce- 

 ment flue running from the boiler cellar 

 up into the square base of the stack."
