714 REPORT— 1898. 



whole scheme of the Committee's inquiries includes a number of subjects, 

 thus appealing to persons interested and capable of rendering assistance 

 in various ways, it is not considered necessary for each observer to deal 

 with them all. Having regard to the movements of population and the 

 spread of education, some subjects, such as current traditions and beliefs, 

 and dialect, are more immediately pressing than others equally important 

 for the purposes of the Committee. 



10. Moreover, it is a question whether the time has not arrived for 

 considering some practicable suggestion for employing a paid and expe-. 

 rienced assistant to make observations in parts of the country which may 

 be expected to yield results of special value for the inquiries. 



11. The grant appropriated to the Committee at the Toronto meeting 

 has not been drawn, and some balance remains in hand from that appro- 

 priated at the Liverpool meeting. The Committee asks to be re-appointed 

 and permitted to use this unexpended balance, and to be provided with a 

 further grant, so as to have at its disposal the total sura of 501. during 

 the coming year.
