Tis not in mortals to COMMAND success, but we'll do 

 more, Sempronius, we'll DESERVE IT. — Addison: Cato. 



For the Amateur. 



Those who wish to cultivate orchids 

 may obtain vigorous specimens of sev- 

 eral kinds of Cattleya already potted and 

 ■established for about $2.50 each ; or in 

 the spring and summer, when shipments 

 •of freshly gathered plants arrive, they 

 may be bought for $1.50 to $2.50 each, 

 or a box containing about forty for 

 $65.00 to $75.00. The latter are not 

 potted but are sold just as they are when 

 received. 



They will grow well in any ordinary 

 greenhouse, except in one with a north- 

 ern aspect. The glass should be lightly 

 shaded during the spring and summer, 

 while the atmosphere and plants should 

 he kept moderately moist and amply ven- 

 tilated at all proper times. A sufficiently 

 high temperature at night is from sixty 

 to sixty-five degrees, Fahrenheit, and for 

 the day a correspondingly higher tem- 

 perature. 



For potting, use soft, fibrous peat with 

 a sprinkling of live sphagnum moss and 

 a few pieces of charcoal, first draining 

 the pots -or pans with potsherds. The 

 peat or compost must be pressed around 

 the plants so that they may be perfectly 

 firm, for no orchid will thrive if left loose 

 or rickety in the pot. If these orchids 

 are treated as well as other flowering 

 plants generally cultivated the beauty of 

 their magnificent flowers will recompense 

 the owner for all his care and attention, 

 while the plants themselves will last for 

 many years. 



are a joy forever to the lovers of good 

 lenses. There are some of us who 

 really love the lens and would get as 

 good as possible even if it wouldn't 

 take a better photograph than a 

 cheaper grade. Seems rather "tough" 

 to always be appreciated for what we 

 do, and not intrinsically for ourselves. 

 Of course, I am merely speaking for 

 the lens ! 



But combining doing and being, in 

 excellent qualities, well what more can 

 you ask? 



Yes, one thing— for the catalogue. 



An Attractive Catalogue of Lenses. 



The Bausch & Lomb Optical Com- 

 pany has recently issued a beautifully 

 illustrated and well printed catalogue 

 of lenses. Their Tessars and Protars 



These Kind Words are Appreciated. 

 I enjoy the magazine very much. — 

 H. M. Hflling, Portland, Maine. 



I really think the magazine is won- 

 derful. — Earl Lynd Johnston, Evans, 

 Colorado. 



I enjoy the magazine and find it 

 helpful in my nature work. — Mrs. II'. 

 K. Harrington, Andover, New Jersey. 



I take great pleasure in reading the 

 interesting and valuable magazine 

 which you are editing. — /. R. Quirk. 

 Managing Editor "Popular Mechanics," 

 Chicago, III. 



I had all my magazines from April, 

 . S, at my school, which burned in 

 January, so I lost all of them. I prized 

 them highly and used them in my 

 work. My pupils liked to read them 

 and hunted for specimens of things 

 described. The one copy in which 

 galls were described gave us some 

 excellent stud}- and the pupils found 

 plenty of specimens which we used. — 

 Ellen Moorhousc, Albion, Indiana.
