peninsula. A second peninsula of apparently .similar origin but without 

 any hills, lies to the east of the town, forming the limits of Caneabato 

 cove. To the west of Tacloban the first low ridge consists of a series of 

 sedinientaries very little exposed, but giving evidence of containing sand- 

 stones and some limestones. The direction of this ridge is about north 

 30° west. Looking across the straits to the north of Tacloban on the 

 Island of Samar, there is a conspicuous hill showing a high escarpment, 

 well toward its upper portion. This escarpment is due to the weather- 

 ing of a thick bed of variable sandstone and conglomerate. In passing 

 through the straits between Samar and Leyte, in the portion which has 

 approximately a north south direction, one may observe outcrops of sedi- 

 mentary beds dipping at low angles to the eastward. These are imper- 

 fect sandstones and nodular and concretionary argillaceous beds. The 

 many changes in the direction of the channel in this part are due to 

 the development of the channel by erosion along the strike of the least 

 •resistant beds which have an eastward dip and a strike of about north 30° 

 west. The topography of the shores and the islands in the straits shows 

 a series of hills or ridges and the channel occupies the lowest valleys be- 

 tween them, passing in a zigzag direction. 



This series of sedimentary beds may best be studied on the Island of 

 Samar where it contains some heavy limestones. Besides a numl^er of 

 sea cliffs which were seen in the small islands along its western shore, 

 exposures were studied at Catbalogan and Calbayog. The formation is 

 probably very extensive in Samar where its history may some day be 

 worked out in detail. It is but slightly represented in the northeastern 

 part of Leyte, and there is little certainty of correlating it with the 

 sedimentary formation in the southwestern districts of the island because 

 of the wide belts of the northeastern plains and the Central Cordillera 

 which intervene. Nevertheless, the idea suggests itself that the sedi- 

 nientaries of western Samar and southeastern Leyte belong to the same 

 series which at present are not classified closely as to age, but which are 

 now called late Tertiary. 



NORTHEASTERN" PLAINS. 



This district is the part of Leyte best adapted to agriculture because 

 of the character of its soil and the general level surface of the land. It 

 lies between the northeastern semimountainous district and the Central 

 Cordillera, having considerable seacoast on Carigara Bay, and a longer 

 coast line on the Pacific Ocean between Palo and Abuyog. Roads are 

 being built to connect Carigara and Tacloban by the way of Palo, and to 

 extend from Palo through Tanattan and Dagami to Burauen; and grad- 

 uallj' this system will extend along the coast as far south as Abuyog, and 

 have branches to all the important centers of population. Carigara is
