The fourth report appeared in May 1892, and was edited by 

 Mr. Chadwick. In connection with this the late Mr. Thomas 

 Tate, an ardent petrologist, had visited the Lake District and 

 reported upon the microscopic structure of the various rocks 

 which occur there. This was of great assistance to the Com- 

 mittee in their work, as several of the ice-borne boulders with 

 which they had to deal originated from that neighbourhood. 

 In consequence of Mr. Chadwick leaving - the country on 

 account of ill-health, the secretaryship fell into the hands of 

 Mr. Thomas Tate, whose extensive knowledge of the micro- 

 scopic structure of rocks proved of great service. Mr. Tate 

 edited the reports until the date of his death, and under his care 

 the Committee's fifth, sixth, seventh, eig'hth, ninth, and tenth 

 lists appeared. In these later reports not only were the 

 measurements and other particulars of the masses of stone 

 given, but their bearing - on the geological history of the county 

 was referred to, in this way greatly adding to the interest and 

 value of the lists. 



In 1893 the Committee's seventh report appeared. This 

 contained several valuable records by the Rev. W. R. Bell, 

 Mr. John Burton, Mr. C. W. Fennell, and Mr. James Spencer. 

 Mention is also made of the fact that an ' East Riding Boulder 

 Committee,' consisting of Hull men, had been formed for the 

 thorough examination of the boulders of that area. From 1893 

 onward the East Riding Committee's records have formed a 

 more and more important feature in the County Committee's 

 report. The eighth report (October 1894) is principally remark- 

 able for the lengthy list of boulders in the Barnsley neighbour- 

 hood, submitted by Mr. W. Hemingway, and for the particulars 

 supplied by half a dozen members of the recently-formed East 

 Riding Committee. The following report, besides containing 

 many records supplied by Messrs. J. Burton, R. Law, and 

 others, includes two tables, in which no less than .2,070 boulders, 

 each being over a foot in diameter, and occurring on the coast 

 between Withernsea and Hornsea, are enumerated and classi- 

 fied. This was the work of the East Riding Committee. The 

 tenth report, Mr. Tate's last, was undoubtedly his best. A great 

 impetus had been given to the work of the Committee by the
