and succeeding pages will show how earnestly it strove 

 to develop this branch of industry, as the climate and 

 soil of the south of Ireland seemed most favourable

 towns and cities, for the promotion of husbandry and 

 agriculture, which might establish communications

 There is a reference to these maps in Dean Swift's 

 correspondence, in a letter of 25th December 1734, 

 from the Rev. Thomas Sheridan to Swift. 1

 that he employed thirty hands in turning out chimney 

 pieces, tables, mortars, tombstones, &c. He had also 

 brought to perfection the boring of marble pipes, 

 which served to convey water underground and from 

 the tops of houses. The firm had executed an order
