THE GARDENER'S MONTHLY 



[Jj9rt7, 



gardeners, and that through many discourage- 

 ments he still keeps up a very interesting green- 

 house establishment, and therefore speaks of 

 steam boilers, hot water boilers, and the relation 

 of gardeners to their employers, from actual ex- 

 perience. 



In regard to this boiler question, we are not 

 disposed to grant it much space, because the 

 principles can be readily learnt from any ele- 

 mentary work, and the practice is so varied and 

 varies so much in results by incidental circum- 

 stances seldom noted by ordinary observers, 

 that very little actual profit comes to the reader.

HEATING BY LAMPS. 



BY W. K. GIBSON, JACKSOK, MICH. 



An article in the January number of your 

 magazine, on the subject of heating by lamps, 

 has led me to send you the following plan of a 

 cheap and efficient stove for heating small struc- 

 tures and protecting hot-beds in cold nights, as 

 well as furnishing extra heat in greenhouses in 

 very cold weather : 



^

First take an ordinary single coal oil stove, 

 which may be procured at any of the hardware 

 stores, then have made to fit the top of it a 

 heater of galvanized or sheet iron, as shown in 

 the above diagram. 



A is the outside cylinder of ten-inch diameter 

 and eighteen inches long, with a two and a half 



inch opening in top, 5, for escape of smoke, etc. 

 Upon this opening a pipe may be fastened, pass- 

 ing to the outside or into the chimney. C is an 

 opening in the bottom of about six inches diame- 

 ter, or large enough to cover the lamp of the 

 stove. D is an inner cylinder eight inches in 

 diameter and fourteen inches long, and so 

 secured that its top and sides are one inch from 

 the outer cylinder, except at the bottom, which 

 would be three inches from the bottom of the 

 outer cylinder. From near the bottom of the 

 inner cylinder leads the cold air pipe E, and 

 from the top the hot air pipe F, each passing 

 through the outer cylinder and being three inches 

 in diameter. The operation of generating heat 

 is seen at a glance. The hot air and smoke from 

 the lamp passes between the two cylinders, 

 heating both, and we not only have radiation 

 from the outer cylinder, but the heated air thrown 

 out from the inner one. 



If more heat is desired a double stove can be 

 used, and in that case the heater can be made 

 of oval shape with two holes in the bottom. 

 This heater can be used for bed rooms, and the 

 smoke pipe, if carried into the chimney or into 

 another stove pipe, will convey off all smoke 

 and unpleasant odor. It is not intended that 

 the heater shall be made exactly of the size and 

 measurement here eiven. 



EDITORIAL NOTES. 



Variegated Oraxge Tree.— At a recent 

 meeting of the Florida State Agricultural Soci- 

 ety, Mr. I. Bidwell, of the Arlington nurseries, 

 exhibited a noble specimen of the variegated 

 orange, which had the fruit as well as the leaves 

 of various colors. It was good to eat, and beau- 

 tiful to look upon. 



Insects on Roses. — There are many little 

 plagues to the rose culturist, especially to those 

 who may have a few plants in pots. Dingee 

 & Conard in their admirable "guide to rose 

 culture," just issued, have the following note 

 about the two worst pests. Coming from a firm 

 that makes a specialty of rose growing, it will 

 tell all that is probably known of the subject : 



" Red Spider is a very minute insect, first ap- 

 pearing on the under side of the leaves, and though 

 difficult to to see unless present in considerable 

 numbers, its effects are quickly noticeable by the 

 browned or deadened appearance of the leaves.
