at the various summer schools, in which instruction is 
largely given by indoor lectures and exercises, are not in- 
cluded. 
A cooperative statement of this kind is in the interest 
of harmonious competition and of good fellowship on the 
part of the contributing institutions ; and it is particularly 
in the interest of teachers and students all over the coun- 
try to have the varied opportunities for field study thus 
conveniently set forth for their selection. 
In order to encourage the taking of field courses in this 
field science, twenty-five well known colleges and universi- 
ties authorize the announcement that they will, under cer- 
tain conditions, give credit to any of their students who 
take summer courses, even at other institutions. This is 
a broad-minded development of the inter-university spirit. 
It is probable that many colleges not in this list will make 
the same liberal arrangement with any of their students 
who wish to utilize the summer vacation for geological 
study. 
It has been suggested that the Intercollegiate Appa- 
lachian Course for the coming summer be replaced by an 
Intercollegiate Mississippi Valley course in the summer of 
1906. It has been further suggested that a summer field 
meeting of "Section E'' (geology and geography) of the 
American Association for the Advancement of Science be 
held at Syracuse. X. Y., in the latter 'j)art of the week that 
the Appalachian course o])ens in that interesting district. 
The Sectional Committee has the plan in discussion, 
with authority from the General Committee to hold sum- 
mer meetings when and where it wishes. 
Since the cliange of the .Vssociation meetings from sum- 
mer to winter. Section E. had lost the benefit and pleasure 
of the field excursions that always used to be planned in 
connection with its sessions, and an experiment in the way 
of a return to the wholesome habit of field meetings seems 
well worth Avhile. 
With Regard To Portage Crinoids. 
In a recent contribution to the American Museum of 
Natural History bulletin, professor Whitfield has pointed 
out that the Cvathocrinus ornatissimus Hall, which in gold
