Here are Poinsettias and Romans in Inexpensive Baskets. 



and scales should be deceased. If any 

 show signs of life, apply a second dose 

 a few weeks later. Don't trust the 

 fumigation to assistants. Do it your- 

 self and keep any cyanide securely 

 locked up." 



C. B., whose trouble was with orange 

 trees badly infested with scale and 

 mealy bug, asked how he could rid his 

 trees of these pests and I advised the 

 use of the gas with an all-night expo- 

 sure. At the strength recommended, no 

 harm could come to the orange trees. 

 In California they are frequently fumi- 

 gated with much heavier doses for San 

 Jose scale without any injury resulting, 

 the exposure, however, being of short 

 duration. I would have hesitated seri- 

 ously about advising any all-night expo- 

 sures for a mixed assortment of plants 

 such as Mr. Merrill grew, without con- 

 siderably reducing the dose. 



The general plan when using hydro- 

 cyanic acid gas among mixed plants, 

 or those which are naturally somewhat 

 tender, is to give an exposure of 

 only twenty or thirty minutes, after 



which the ventilators are opened 

 from outdoors. Dangers of injury 

 are then greatly minimized. The 

 colder the house the less danger there is 

 of injury. On carnations gas usually 

 takes the color out of the flowers and 

 is liable to scorch the tips of the young 

 shoots. 



For keeping spider in check on carna- 

 tions spraying with salt and water is 

 an excellent thing to use. Once a month 

 use a 3-inch pot of salt to five gallons of 

 water. 



Such plants as smilax, Sprengeri, 

 plumosus, geraniums, especially the 

 scented-leaved ones; snapdragons, free- 

 sias, mignonette, palms, ferns and all 

 orchids are comparatively delicate and 

 I would not advise the use of gas among 

 them except in extreme cases and then 

 only in cool weather and by experienced 

 hands. Lettuce, cucumbers, tomatoes 

 and other forcing vegetables are deli- 

 cate and gas should never be used for 

 them. 



In using gas again, if you have facili- 

 ties for opening your ventilators from 



outdoors, give twenty to thirty minutes 

 exposure only. 



Tne proper use of gas is not yet well 

 understood. That it is a valuable fumi- 

 gant none can deny. The views of other 

 Review readers on tnis subject who are 

 using gas would be of great interest 

 and benefit to a large circle of readers, 

 and I hope we may hear from them.
