On page 821 of the Btarr-Eering-Freeiian report the followijng state^nt is laade: 

 wifhere these coatotirs are shcfwn as a succession o£ long dashes, the 

 mirface of the g3:»otmd iiat«* is well establidbedj ishere shoim as dotted 

 lines^ as on soase of the areas covered by the laoraine and the thick 

 layers of till on the northerly portion of the islandj^ the location 

 of the sixrface of the imter table is soiaewhat conjecttiral, becanse 

 fer existing ifells ifere foand there of sufficient depth to reach the 

 true tmter table and the cost of the necessary wells, some of wMch 

 would have had to be ful3y ISO feet in depth, "was prohibitive* The 

 surface of the grotmd water, which is held by the fine coii?5act aaaterial 

 forming the moraines and the l^^ers of till that partially cover the 

 northerly portion of the island, are not shown on this 190S contotir map* 

 Since, in general, it appears that the water f r<m these elevated strata 

 is slowly percolating into the sands and gravels that, as the geolo- 

 gists have shown, underlie the aantle of till, to isfcat sdght be teriaed 

 the lower water table, iihich is the surface shown by the contours* « • 

 The strata between these two saturated layers are, in souse localities, 

 coKDletely saturated, the difference between the elevations of the two 

 water tables reparesenting the loss of head through vertical seepage j 

 but in many localities the interveniiag sands were found to be oaxLy 

 partially saturated^* 



In recent years wells of the requisite depth have been drilled in some of 

 the doubtful areas shorni on the 1903 map* The results are given on the contcwr 

 map acconpaaaying this report (Plate 1) « Soiae of these wells stmck water at two 

 levels before the main water table was reached, conf iarndng the observation isade
