Taytay is situated on the eastern border of the broad Mariquina 

 Valley, and at the western foot of the upland which extends from Anti- 

 polo into the Binangonan Peninsula. TJie church, which may be re- 

 garded as the nucleus of the settlement, stands on a low hill which is 

 the western end of a peninsular area, intermediate in elevation between 

 the valley and tire hill country. (Plate VIII, fig. 1.) The town is 

 nearly surrounded by lowlands devoted to the cultivation of rice. To 

 the east of the town there are hills covered with cogon grass. Along 

 the streams there is a giowth of bai^iiboo and in the valleys Ijetween the 

 hills a variety of trees are found, which extend irregularly up the hill 

 slopes. (Plate I.) 



There are two streams which pass through Taytay. One comes from 

 the north and has its course through the western part of the tov\'n. The 

 other comes from the east and passes through the southern border. 

 They join in the southwest part and the resulting stream continues to 

 Bay Lake (Laguna de Bay). There is also a cut-off from the Cainta 

 River which comes from the west but this is practically dammed now 

 by the railroad grade. During the dry season the water of the streams 

 stands in stagnant pools or entirely disappears, l)at in the wet season it 

 has a considerabe volume and affords communication to tbe lake by 

 banca. 



The main routes of travel from T'aytay are westward to Cainta and 

 across the Mariquina Valley towards Pasig and Manila and eastward 

 to Antipolo. There is also a road soutliward to Angono and Binan- 

 gonan, but it is little traveled. Banca traffic to tbe lake for fishing is 

 important during the wet season. Taking these facts into consideration, 

 it is easy to understand why the growth of the town in former times 

 lias been along the roads to the westward in tlie direction of the rice 

 fields, and especially toward the juncture of tlu> streams where fish are
