328 BOTANICAL GAZETTE. 
Botanical Club only, to one of the most interesting collecting grounds of the 
region, giving an opportunity to see the country and to botanize throughout 
the trip. The long excursion for Saturday has not been definitely decided upon 
as we go to press, but whether it be to the Saginaw valley or along the Detroit 
river an opportunity will be afforded the botanists to make a detour for exam- 
ining the vegetation and collecting. The excursion after adjournment to Mack- 
inac island and Sault Ste. Marie will give a rare opportunity to see a new flora 
and enjoy a delightful trip. 
The meetings of the Club will be held during the week, beginning on 
Thursday (and not on Tuesday, the 25th, as erroneously announced in the Per- 
manent Secretary’s circular), The time and place will be given in the daily 
fee gre as well as all other announcements for the Club 
tw oubtless not be superfluous to say a little regarding the organiza 
tion and ipa of the Club. It had its inception at the Minneapolis meeting 
in a desire to secure a larger attendance of botani sts at the meetings of the 
tical chee ig The Club is not encumbered with oaenrbee 5 ” -laws or 
formalities. Only members of the Association who express an interest in botany 
are eligible to membership, and the only other requirement is venitatle The 
meetings are held at such times as will not interfere with those of the Associa- 
tion, usually at 9 to 10 a. m., on Thursday, Friday, and the succeeding Monday 
and Tuesday, 
It is earnestly suggested that only botanical papers of considerable weight 
and importance be submitted to the general Association, and that all others be 
read before the Club, which will give them quite as good a hearing and the 
certainty of a more earnest discussion.
