A. concolor 2,389 are living and 834 are dead. Of the 500 Pseu- 

 dotsuga taxifolia 355 are living and 145 are dead. It may be 

 thought that this is a large mortality, especially so with the 

 Concolorsand Douglas Firs. But, astheseareall wild seedlings, 

 a considerable shrinkage is to be expected. 



Making the comparisons more definite it may be stated in 

 round numbers as follows: Of spring-planted trees: sixty per 

 cent. 01 A. concolor have died ; thirty per cent, of Junipers 

 have died ; twenty-three per cent, of the.P./w»£*«jhavedied. 

 Of fall-planted trees: twenty-five per cent, of A, concolor; 

 twenty-nine per cent, of P. taxifolia, and twelve and one-half 

 per cent, of P. pungens have died. The above seedlings were

 their well-being will also be noted. . 



Though the members of this family in general are not 

 specially particular in regard to soil, yet there are a few gen- 

 eral rules to be observed — for instance, the soil should be 

 coarse and open, to allow the water to pass through freely, and 

 the pots or pans should invariably be well drained by means 

 of a layer of potsherds, cinders or charcoal. A liberal supply 

 of water should be given during the growing season, and after 

 the plants become somewhat pot-bound an occasional watering

 used too strong. During- the winter somewhat less water will

of various sizes, from six to ten inches in height. I wish to 

 add, in fairness, that I received from another Colorado collec- 

 tor September 19th, 1889, 1,000 P. pungens of a larger size, 

 from one to two feet in height. As might be expected they 

 were more stunted and unpromising. The mortality has been 

 heavy upon this lot, rising above fifty percent., or, stated more 

 exactly, 527 are dead and 473 alive at this date. For myself I shall 

 continue to advocate the planting of conifers in August and 

 September. For long distances, it is only necessary to guard 

 against heating and drying. Success presupposes care.

A Few Strong-growing Adiantums. 



'THE extensive Maiden-hair family presents much diversity 

 *■ in sizes and forms among its many species, all of which 

 are beautiful, and many of them notably so. It is not intended, 

 however, in this connection to present a catalogue of species, 

 but to invite attention to a few of the stronger growing sorts, 

 many of which flourish under cool-house treatment, or in an 

 ordinary conservatory temperature. Of course all strong- 

 growing Adiantums are not greenhouse sorts, as some of 

 them do much better in a warm-house, but where such varie- 



be required and the manure may be entirely omitted, as they 

 make little active growth at that season. 



Among the older species, A. trapeziformc occupies a promi- 

 nent place, and is surpassed by few when well grown. It is easy 

 to manage and makes a shapely plant, the leaf-stems being so 

 stiff that they seldom need staking. Its fronds attain a height 

 of from three to four feet, the pinnae being very large, light 

 green in color and trapezoid in outline. A. trapeziforme is of 

 West Indian origin, and has been in cultivation for many years. 



A. formosum is another species of special elegance and 

 utility, and is well adapted for cool-house treatment. Its 

 quadripinnate fronds sometimes reach a height of four feet, 

 though they are more often seen two or three feet in height. 

 The pinnae are much smaller than those of the preceding 

 sort, and the fronds are somewhat stiffer, and are produced 

 from very free-growing rhizomes, the latter being often found 

 coiled around the interior of the pot from top to bottom. It is 

 a native of New Zealand. 



A. Peruvianuiu is an excellent sort of more recent introduc- 

 tion than the above, and, as its name indicates, was first found 

 in Peru. It has long fronds of gracefully arched habit, clothed 

 with very large pinnules of bright, light green, and will make 

 satisfactory progress in a warm house, where its growth in a tern-
