The Weekly Fforists^ Review* 



August 81, 1911. 



the description indicates, house No. 7 

 is of full width at one end only, the 

 number of returns should be reduced 

 proportionately at the narrow end. In 

 house No. 8, 22x48 feet, one 2-inch and 

 six 114-ineh pipes will be required. 



To heat the range described, a sixty 

 horse-power boiler will be desirable. 

 Just how the main flow pipe should be 

 run will depend upon the construction 

 of the houses. If feasible, run a main 

 along the ends of the houses, starting 

 with a 5-inch and reducing to 4-inch, 

 3-inch and 2 1/^ -inch after taking off 

 houses 5, 4 and 3, respectively. In each 

 house carry the main overhead and dis- 

 tribute the returns under the benches 

 and on the walls. 



ErFECT or CINDERS ON PIPE. 



Will you kindly explain what effect 

 coal cinders will have on iron pipe, gal- 

 vanized or otherwise, when used in green- 

 houses for posts, purlins, steam pipes 

 and other purposes? We are informed 

 that cinders have been known to "pit" 

 railroad rails when these have been al- 

 lowed to remain in cinder piles for a 

 year or two. We ask this information 

 through your columns, knowing that in- 

 formation that is valuable to us will be 

 valuable to others. M. F. & V. C. 



When iron pipe is set in cinders it 

 seems to undergo a chemical action, even 

 when galvanized, and this action appears 

 to be more rapid than when the pipe is 

 standing in common earth or gravel. It 

 is always desirable to set greenhouse 

 posts in grout, but cinders and gravel 

 «an be mixed in equal parts and used 

 with cement without fear of serious in- 

 jury to the posts. 



IN WASHINGTON STATE. 



We are building four greenhouses, 

 ^jach 15x200 feet. They are connected 

 houses, of wood and metal construction. 

 We have a steam plant and will carry 

 about fifty pounds of steam, and we 

 wish to know how many 1^-inch returns 

 will be required for each house in order 

 to be able to maintain a temperature of 

 55 degrees in the coldest- weather. Our 

 winters are not severe, but we occasion- 

 ally have zero weather for a few days 

 during the season. We will use a. 2^2- 

 inch flow or supply pipe in the center 

 of each house and the returns will be 

 strung along the pipe supports of each 

 house. The houses will be well con- 

 structed and strictly modern. Please 

 give us the benefit of your experience 

 and information on this point. 



W. W. F. C. 



A 2-inch flow would be amply large 

 for each house, and with four 114-inch 

 returns would maintain the temperature 

 mentioned in all except the outside 

 houses, which would require an addi- 

 tional return, especially if they have 

 any glass in the outer walls. 



East Las Vega^N.M. — Perry Onion, 

 of the Las Vegas Greenhouses, has re- 

 ceived his son, Charles, into partner- 

 ship, and the firm name is now Perry 

 Onion & Son. They removed their 

 downtown headquarters, August 15, to 

 507 Sixth street, in the best business 

 district of the town. They have added 

 to their equipments an elegant new 

 plate glass cut flower box and several 

 display cases for ribbons and supplies. 

 They also expect to handle a full line 

 •of seeds.

are all satisfied with ttie results it has given, and many 

 duplicate i rders is the proof. This Valve will main- 

 tain a steady pressure on the low side, no matter 

 how the initial pressure fluctuates. By carrying 40 or 60 

 pounds pressure on the boiler and setting the valve to 

 carry 5 or 10 pounds on the line, you always have a 

 reserve to fall back on in raxe of a sudden drop in tem- 

 perature. Our nm^ir oataloKue Is lust out and if
