outside of the storage room, from which 

 four expansion valves lead to the sepa- 

 rate rooms. Direct expansion is used 

 in all of the rooms and a 2-inch suction 

 line returns to the compressor. 



Booms 1 and 2 are used for cooling and 

 storing cut flowers and are maintained 

 at a temperature of 38 to 40 degrees. 

 The expansion lines, which are all 2-inch 

 extra heavy galvanized iron pipes with 

 soldered connections, encircle rooms 1 

 and 2 on three sides, the expanded gas 

 entering at the top and circulating down- 

 ward in such a manner as to form no 

 pockets for the accumulation of am- 

 monia. There are no elbows in the 

 piping, all being 90-degree bends, and 

 no joints except the flange fittings. At 

 the lowest point in the system, a %-inch 

 oil drain is provided to take out any ac- 

 cumulation of oil in the system. The 

 piping is hung on galvanized iron brack- 

 ets with 7-inch centers, in a substantial 

 manner, and to engineers gives the im- 

 pression of a most permanent and satis- 

 factory installation. 



Aside from the ammonia expansion 

 coils in rooms 1 and 2, there is an ad- 

 ditional provision for the maintenance 

 of low temperature during periods when 

 the compressor is not running. This 

 is in the shape of a galvanized iron 

 tank containing brine which is cooled 

 by direct expansion and is a source of 

 refrigeration when needed. The tanks 

 are hung on galvanized iron brackets 

 from the ceiling. The location of the 

 tanks is clearly shown in Fig. 10. 



The expansion coils in rooms 3 and 4 

 diflfer somewhat from those in rooms 1 

 and 2, in that they are not provided with 

 brine tanks and are located both on the 

 ceiling and on the side walls. In details 

 of construction the piping is similar to 

 that already described, being 2-inch gal- 

 vanized iron with soldered joints and ar- 

 ranged with particular reference to the 

 drainage of ammonia downward from the 

 top to the lowest point. 



These rooms are known as the lily bulb 

 rooms, and a temperature of 24 degrees 

 is maintained, the object of the low tem- 

 perature being to retard the growth of 

 the bulbs stored here, making it possible 

 to hold Easter lily bulbs and valley pips 

 dormant and maintain a supply of cut 

 flowers the year around. 



For purposes of storage, the bulbs 

 are put in closed boxes and piled one 

 above the other upon brackets or shelves, 



having a space between each box so that 

 the air can be perfectly circulated and 

 an even temperature maintained. When 

 taken out of storage the bulbs are not 

 planted at once, but are put through 

 a process of gradual thawing out. 



You are doing splendid work with the 

 Review. I have had all the trade papers, 

 but yours is the only one I have stuck 

 to. Find enclosed my dollar for an- 

 other year, and I think it is money well 

 spent. — H. C. Buchelee, Sewickley, Pa. 



A FLYING TRIP TO CHICAGO. 



How the 'Windy Qty Looks to Wau Penn* 



A baseball team of Philadelphians 

 gathered in the Art Institute at Chicago 

 on Wednesday morning, March 25, to 

 witness the opening of the national rose 

 show. Frank P. Myers, A. Farenwald 

 and Martin Samtman came over on the 

 sixteen-hour train; the limited brought 

 William P. Craig, Clarence Upton and 

 J. W. Young, while E. J. Fancourt, J. J. 

 Karins and S. S. Skidelsky came from . 

 nearby cities, where business had called 

 them. Cordial greetings were exchanged 

 with Secretary Hammond and then came 

 the interesting task that became pleas- 

 ure of seeing all that could be seen in a 

 brief period of time. 



The National Rose Show. 



The rose show was truly a national 

 affair, east'ert and western growers meet- 

 ing in friendly rivalry as they had never 

 met before. ' 



The view from the gallery overlooking 

 the exhibition hall was most beautiful. 

 Fancy a long, wide hall, with lofty ceil- 

 ing, large windows, rather high, admit* 

 ting ample light and air ; the hall, a work 

 of art itself, adorned with handsome, 

 statuary of heroic size in sufficient num-' 

 bers to the immense vases of the queen 

 of flowers visible everywhere, not 

 crowded together, but standing well 

 apart on the floor or on low tables, show- 

 ing color, size, stem and foliage to ad- 

 vantage. Fancy all this and you see the 

 Chicago rose show of last week from a 

 spectacular standpoint. But you want a 

 closer view.
