possible condition when the time for 

 planting arrives. If sown too soon the 

 plants either become overgrown to such 

 an extent that they receive a severe check 

 in being transferred to the open ground, 

 or they become so hampered in tight 

 quarters that they become hard and 

 stunted and take so long to make a start 

 after planting that much valuable time 

 is lost in place of time being gained by 

 making an early start. 



The idea should be to regulate the 

 sowing so as to have the plants just 

 large enough but at the same time have 

 them in a healthy, free-growing state. 



We have often seen such subjects as 

 egg plants and peppers sown the first 

 week in April beat plants from seed 

 sown the beginning of Marcii. As these 

 are rather tender subjects, they cannot, 

 as a general rule, be trusted outdoors 

 much before the end of May, so by 

 sowing at the end of Marcn it gives two 

 months from sowing to planting out. 

 This allows nice time to get the plants 

 in the best possible order, if proper care 

 is given and the proper facilities are 

 available. 



Cabbage and cauliflower plants cau 

 be grown large enough in seven weeks 

 from time of sowing but to give time 

 for proper hardening oflf eight weeks had 

 better be allowed. These being hardier, 

 may safely be planted from two to three 

 weeks earlier than egg plants or peppers. 



Lettuce plants in nice order for plant- 

 ing can be grovra in six weeks from time 

 of sowing and may, as a rule, be set 

 out about the same time as cabbage. 



The time of setting out is apt to vary 

 somewhat on the warmth of the season, 

 but seldom enough to affect the condi- 

 tion 01 the plants. The proper harden- 

 ing off of all vegetable plants previous 

 to setting out should always be carefully 

 attended to as it insures against check 

 and enables the plants to better with- 

 stand the variations of temperature 

 which are liable to occur.

PIPING FOR FOUR HOUSES. 



I am building four 50-foot houses ; 

 two houses ten feet Avide, four feet to 

 eaves, seven feet to ridge; one house 

 fourteen feet wide, four feet to eaves, 

 eight feet to ridge; one house sixteen 

 feet wide, four feet to eaves, nine and 

 one-half feet to ridge, with two feet 

 glass on east side, for carnations. The 

 houses run north and south, with boiler 

 shed and workroom on north ends of 

 houses. The houses have glass in south 

 ends from gutters and eaves up; the 

 outside walls are double-boarded with 

 paper between. Each house will be sep- 

 arated from the others by one thickness 

 of siding. I want to know how many 

 runs of 114 -inch pipe are needed for 

 each house, also how large the pipe un- 

 der the ridge ought to be and what 

 horse-power steam boiler I need to 

 maintain 55 degrees to 60 degrees at 

 zero outside. H. T. 



Each of your small houses 10x50 feet 

 can be piped with a l^o-inch flow under 

 ridge and six 1 14 -inch returns on side 

 wall or under benches. 



The 14-foot liouse should have a 2'- 

 inch flow or riser under lidge and eight 

 11/4-inch returns, while the 16-foot house 

 should have a 2-inch flow and nine 1V4- 

 inch returns. The combined require- 

 ment of the four houses is less than 

 1,000 square feet of radiation. A boiler 

 with 130 square feet of lieatiug sur- 

 face should be ample to provide steam 

 for these houses. This would be equiva- 

 lent to about twfhe liorsc-powcr.

MORE RADIATION NEEDED. 



I have a greenhouse 20x50 feet, side 

 walls four feet, sasbbars twelve feet, 

 which I am going to extend fifty feet 

 this season. I have a hot-water system 

 at present and heat my dwelling with 

 the same riser that heats the green- 

 house. My piping arrangements are as 

 follows: A 3-inch riser six feet liigh 

 to ell, then six feet to branch for dwell- 

 ing, continuing with 2V.-inch pipe into 

 greenhouse, where it branches into two 

 2-ineh pipes to right and left tiiat feed 

 a coil of three lJ{>-inch flows arranged 

 above three IV^-inch returns on gutter 

 posts. The system has worked with jier- 

 fcft satisfaction during the past season. 



When I extend the house fifty feet 

 farther, making a house 100 feet long, 

 will this arrangement of pipes give the 

 same satisfaction as before? Would it 

 be more satisfactory if I should run 

 two 2-inch flows along each purlin to 

 feed four ll^-inch returns on side walls, 

 or would one 2i^-inch flow lie better 

 than two 2-incli flows? Will the 3- 

 inch riser mentioned be large enough to 

 furnish l)etween 600 square feet and 

 700 square feet of radiation? 



In my dwelling 1 heat one room 12x 

 27x9 feet, separated by a screen parti- 

 tion into two rooms, with 99 s(|iiaro 

 feet of radiation. The room faces 

 north, is exposed on three si.ifs, has 

 four common size and two large size 

 windows and one outside door. We are 

 much exposed to northwest winds. Dur- 

 ing the past winter I found we had not 

 enough radiation. How much r;uliation 

 will I need to keep the dwelling at 70
