O OECHID-GROWEB S MANUAL. 



travellers and collectors who have added so largely to our 

 knowledge of Orchids, and who have laboured so arduously 

 and incessantly to enable us to enjoy the beauties of the 

 choicest productions of the vegetable world, without the dangers 

 and difficulties with which they had to contend. Many of 

 them, alas ! have fallen victims to the fatigues of the under- 

 taking, and the pestilential climate, thus suffering martyrdom 

 for the cause of horticulture. I allude specially to such men 

 as the brothers Lobb, Hartwog, J. G. Veitch, Colonel Benson, 

 O'ReiUy, the Eev. C. Parish, Pearce, Bowmann, Weir, Hutton, 

 Ki-amer, Porte, Walhs, Linden, Skinner, Hugh Low, Schlim, 

 Warscewicz, and many others who might be named, did space 

 permit. These were men who had in view the advancement 

 of science, and the enriching of our collections with new 

 plants and new forms ; and their example might be followed 

 with advantage by many of the latter day collectors, who, 

 instead of sending home a few plants in good order, allowing 

 the skill of the cultivator to grow and increase them at home, 

 seem determined to exterminate the race of Orchids from their 

 natural localities, without any one deriving benefit thereby ; 

 for when such vast quantities are gathered, they arrive in this 

 country in an almost putrid state, arising from overcrowding ; 

 whUst, had a few dozens only been sent, and that with proper 

 care in packing, they would in all probability have arrived in a 

 living state. 



THE TREATMENT OF TROPICAL ORCHIDS. 



IRCHIDS are divided into two sections, terrestrial and 

 epiphytal. Those are termed Terrestrial that grow 

 in earth ; such are the genera Orchis, Phojits, 

 Calavthe, Bletiii, Cyjiripedhim, Neottia, Goodyera, Epipactis,
