temperature is 55 degrees in the green- 

 house, at 7 'clock in the morning the 

 glass will be heavily frosted. As soon 

 as the sun comes out the ice inside 

 will begin to melt, causing a heavy 

 <iampness in the greenhouse. Many 

 growers usually shut off the heating 

 pipes as soon as the temperature begins 

 to rise, but this should not be done, 

 as the dampness thus kept in the green- 

 house causes the buds to fall off. 

 What should be done is to let the heat 

 on for a while, but open the ventilators 

 slightly, so that the dampness may 

 escape. As soon as the thermometer 

 begins to rise 1 or 53 degrees, open the 

 ventilators more and more, so that the 

 highest temperature of 70 to 72 degrees 

 may not be reached before 11 a. m. 

 The change should also be made grad- 

 ually during the afternoon. From 

 about 2 to 3 p. m. begin gradually to 

 reduce the temperature by lowering the 

 ventilators, never leaving them open 

 until the temperature is entirely down 

 ^0 55, but letting the ventilators go 

 aown by degrees. ^""V^ 



"If it becomes necessary to Water, 

 select only bright days when you are 

 sure that the ventilators may be kept 

 open for several hours at a time. If, 

 after watering, there is any sudden 

 change in the weather, start the fires 

 *t once and leave the ventilators open 

 as long as possible.

ORASSHOPFEBS. 



^. There is complaint of the depreda- 



lons of grasshoppers, which in certain 



!,ections are a plague this year. In 



'uiton county. New York, the like of

^nown, all field crops suffering. Wher-

Kreenhouse people have their troubles.

PLANTS FOR VIOLET HOUSE. 



I am about to plant a house 18x50 

 with single violets. Princess of Wales, 

 a good stock of which I now have, but 

 not enough to fill all beds the first sea- 

 son. I run these at a temperature of 

 42 degrees, which suits them well, and 

 never higher than 45 degrees on the 

 coldest nights in winter. I want to fill 

 up with other crops, with the excep- 

 tion of pansies and myosotis. I should 

 like to introduce sweet peas, stevia. 

 Peach Blossom and Blushing Bride gla- 

 dioli and any otheir cut flowers for which 

 the above temperature will not be too 

 low. At present the benches are raised, 

 but I propose to change to solid beds 

 and heat accordingly. T. E. T. 



You will find Princess of Wales vio- 

 lets succeed better at 40 to 42 degrees 

 than 42 to 45 degrees at night. Still, 

 if you want to grow other plants, the 

 higher figures are to be preferred. The 

 temperature would be all right for 

 sweet peas in the early stages of 

 growth, provided your violets were out 

 of the way about April 1 so that you 

 could advance the temperature to 50 

 degrees at night at the time the sweet 

 peas should flower. Stevia will do all 

 right with single violets; so will the 

 gladioli named, also the large-flowered 

 varieties, such as America, Augusta 

 and Mrs. F. King. These latter would 

 not flower before the end of April. 



Anemones, ranunculi, tritonias, ixias 

 and sparaxis are bulbs which would 

 also succeed with violets. Mignonette 

 and English primroses also succeed in 

 the same temperature. Marguerites and 

 snapdragons do well with 45 degrees 

 as a winter minimum, as do schizanthus, 

 calceolarias and cinerarias, if pot 

 plants are needed. C. W. 



VIOLETS FOB SMALL HOUSE. 



I am just starting in the violet grow- 

 ing business and want to know if you 

 can help me. I have a small green- 

 house, 8x20, with a path one foot wide 

 running lengthwise. I should like to 

 know how many violet plants the house 

 will hold and if a coal oil heater, such 

 as is used for heating a living room, 

 would do to heat the house. I expect 

 to build a larger house next spring and 

 do not want to go to the expense of 

 buying a big boiler for so small a 

 house? R. L. 



A house of the dimensions men- 

 tioned, while it will produce some vio- 

 lets, will not give^ satisfactory returns. 

 Violets need a low temperature, 40 to 

 42 degrees at night. In a large house 

 this can be kept tolerably steady. In 

 a small structure, heated as you sug- 

 gest, temperatures are bound to fluc- 

 tuate wildly, with correspondingly bad 

 results. If you grow single violets, 

 such as Princess of Wales, you can 

 plant 200; if doubles, such as Lady 

 Hume Campbell or Marie Louise, are 

 to be used, twice that number can be 

 housed. Much, of course, will depend 

 on the sire of your plants. C. W. 



Ottawa, Kan. — The city commission- 

 ers' order for walks to be built on 

 Hickory street necessitates the moving 

 of some of the houses of the Lester 

 Greenhouses back of the property line. 



Sherbom, Mass. — The wind and hail 

 storm that passed through here July 12 

 broke nearly every light in the green- 

 house of J. Dudley Clark and damaged 

 it in other ways as well. The heavy- 

 rain that followed the hail added to the 

 destruction.
