8 CONNECTICUT GEOL. AND NAT. HISTORY SURVEY [Bull. 



incurred. This allowance for expenses has been understood to 

 be available for necessary travel, for the employment of steno- 

 graphic or other clerical assistance, or for the employment of 

 students or scientific men of less experience who could do some 

 part of the work under the direction of the responsible investi- 

 gator. In some cases, however, this form of contract has been 

 impracticable, as investigations have been commenced and prose- 

 cuted in regard to which it could not be foreseen how soon they 

 would result in conclusions definite enough for publication. In 

 such cases the agreement has been to pay the investigator a small 

 sum per diem, a maximum limit being prescribed in every such 

 case. 



Each report prepared is published as a separate bulletin, the 

 bulletins being numbered consecutively, generally in the order 

 in which they are received. Each bulletin bears the name of 

 the author or the names of the authors, and each author is 

 responsible for his own work. The bulletins are issued in paper 

 covers, but a part of the edition is reserved for binding. Bulle- 

 tins i to 5 have been bound as Vol. I., and Bulletins 6 to 12 as 

 Vol. II. It is expected that Bulletins 13 to 17 will constitute Vol. 

 III. The bound volumes are especially desirable for public libra- 

 ries and similar institutions, in which complete sets of our pub- 

 lications are to be preserved. The pamphlet form, in which 

 each bulletin is complete in itself, is convenient for the large 

 number of students, teachers, and others who have use for some 

 particular bulletin. The publications of the Survey are distrib- 

 uted by the State Librarian. They are given liberally to colleges, 

 public libraries, geological surveys, and other scientific institu- 

 tions, and to scientific men of repute in the branches of science 

 with which the respective bulletins are concerned. In many cases 

 publications of great value are received in exchange for the pub- 

 lications of the Survey. All books and papers thus received are 

 deposited in the State Library. The publications of the Survey 

 are also distributed liberally to citizens of our own state, par- 

 ticularly to teachers who can make use of them in their work. 

 In the case of persons in other states who are not known as 

 scientific men, and who appear to have no special claim for the 

 donation of the publications of the Survey, the bulletins are sold 

 at prices sufficient to cover the cost of printing and transportation.
