ordinary trip it hardly pays. It adds too much unnecessary weight, 
while a good botanist will probably recognize all the plants he 
encounters even if there be some new to him. 
When it is desirable to take a luncheon along and not convenient 
to carrry it in the small box, it is better to provide a small aversack 
made of light enamelled cloth and carried on the back. It weighs 
only 2 or 3 ounces, comes handy for various purposes, and is pre- 
ferable to adding an extra compartment to box, as this addition, I 
have found, adds more in weight than utility. 
- A good, stout, easy-fitting pair of d00fs or shoes, should be worn 
on a Jong tramp. They should have thick, broad soles, broader 
than the foot, and low, wide heels, for easy walking. English walk- 
ing shoes are excellent for fields and mountain climbing, but as 
many of our rarest plants are to be found in swamps, marshes and 
low, wet grounds, boots, perhaps, on the whole, are preferable to 
shoes for botanizing,—unless one is willing to follow the example of 
an enthusiastic botanical friend, who, in traversing some deep, miry 
swamps, in company with the writer, would deliberately pull off his 
shoes as he came to each swamp, and explore the batrachian wilder- 
ness barefooted. 
Rubber boots, except for a limited period in marshes or swamps, 
should not be worn. They soon become unendurable to wearer, 
and early put him 4ors de combat. 
Light, loose-fitting clothes will be found most comfortable. For 
a trip of several days or longer, flannel shirts are to be recommended, 
—blue or gray is preferable. For alpine botanizing, where the air 
is often exceedingly chilly, a warmer dress is necessary. 
Finally, ere concluding these notes on the outfit, let the young 
collector be cautioned against carrying too heavy a burden on set- 
ting out on an expedition. It is a temptation into whieh young 
botanists are inclined to fall. In the morning in his freshness and 
vigor, the load will probably not seem over heavy, but after some 
hours tramping through tangled swamps, sinking morasses, and over 
dipping bogs, its oppressive weight will be painfully recognized. 
Rather than carry a very heavy box all day, it is better to bring 
in the surplus specimens wrapped in Osmundas, and the bundle tied 
with grasses. I have frequently done this,—the bundle being 
slightly moistened, the most delicate plants can be kept as fresh as 
in box. . 
§ 235. Publications.—r. Syxoptical Flora of North America. 
When thirty-five years ago Torrey & Gray’s Flora of North America 
had been brought down to the end of Compositae, the rapid exten- 
sion of our territories and exploring surveys, brought such an acccumu- 
lation of new material, that these eminent botanists suspended their 
work on the Flora, and, with others, devoted themselves to working 
. up the new species and correcting the old determinations with the 
light afforded by the more abundant and complete specimens. This 
work has at length been accomplished. New species and new gen- 
era will no doubt continue to be added, but the great features of our 
Flora are determined. In the interim Dr. Torrey has departed, 
leaving a name that will ever be revered as that of one who first laid
