expense of my trip to Georgia — $80.69. It is anticipated that fur- 

 ther draft will be made when plans for boring have been so fully 

 developed that they may be advantageously submitted to an engi- 

 neering expert. 



(4) In view of the fact that a site has been found at which the 

 essential natural conditions are realized, and of the further fact that 

 an experienced and responsible well-boring company has such con- 

 fidence in the feasibility of a 6,000-foot hole as to be willing to guar- 

 antee its completion, I recommend that the making of a deep boring 

 be undertaken by the Carnegie Institution. 



(5) I recommend further that the sum of $65,000 be allotted, of 

 which $10,000 be available in the calendar year 1905, and $27,500 

 in each of the two succeeding years. This recommendation does 

 not imply the adoption of the contract plan, the question of business 

 method being left open. 



(6) I recommend that the control and supervision of the work be 

 intrusted to a committee of three persons, one of whom shall be a 

 physicist, one a geologist, and one a man practically familiar with 

 boring operations. 



(7) I submit herewith a discussion of the value to science of the 

 proposed boring, of the considerations affecting the determination 

 of a suitable site, and of the local conditions of the Lithonia district. 



Respectfully submitted.
