158 BOTANICAL GAZETTE. [ June, 
they have in many instances sent their good wishes. It has not been possible 
to use all the material sent in, and a number of the articles have necessarily 
been cut down in order to bring them within our space and to prevent repeti- 
of the special and most approved methods as actually practiced by representa- 
tive botanists. Even with this restriction, and by the utmost ion, thirty- 
ages have not been ample enough for our material, and some interesting 
articles are deferred until the July number. 
Tue GRACE of liberality needs cultivation among botanists who love the 
science lest “exchanging” degenerate into barter. If one exchanges merely to 
increase the aggregate number of species in his herbarium he wofully lessens 
his opportunity for usefulness. Between correspondents it t should not nen neces- 
sary to balance the accounts at the close of each season t ors 
duplicates to correspondents whenever enough has accumulated to make the 
package worth sending. ‘The liberal soul shall be made fat.” 
A STRONG Protest ought to be entered against the practice of sending speci- 
e. 
cialists are usually glad to receive and determine specimens in their depart- 
ments, but they have neither time nor inclination to tie up and perhaps pay 
postage on numerous packages. 
Our PROMISED article un Early American Collectors is crowded out by 
other fresher matter. Those specially interested in this matter will find a most 
entertaining sketch of the aga oe European herbaria of interest to North 
merican botanists in the Am. Jour. Sci., 1, xl. 1-18 (1841) from the pen of Dr. 
Gray*. Mention is there made anaes of the earlier collectors and the herbaria 
where their plants are to be found. 
Do nor collect too narrowly. Remember that the lichens, mosses, liver- 
worts, alge and fungi of your vicinity are of interest to some one whose address 
you can easily obtain, even if they do not interest you. Pick up whatever 
comes in your way, sort it and send the materials to specialists whose work you 
will aid and whose gratitude you will merit.
