4. Road from Santo Domingo to Sabana la Mar. Since the southeastern part of the Dominican Republic consists of great plains, the roads in this region are all perfectly level and less difficult than those of the mountains, but they are little more than trails and the wide savannas make traveling monotonous. The road which turns northeast from Santo Domingo on the left side of the Ozama passes the sugar estates there situated, continues by a wide path through a lightly wooded country to the town of Guerra and shortly thereafter enters upon the Guabatico prairie, which it crosses in its entire width of over twenty miles. The ascent to the first pass, that of the Castellanos mountain, then begins. The descent is as easy as the ascent, a valley is crossed in which the headwaters of the Macoris River are forded, and then follows a long ascent to the second pass. From the foot of the mountain to El Valle and Sabana la Mar the country is wooded and the road level and wide, but so miry as to be practically impassable during the entire rainy season. The distance from Santo Domingo to Sabana la Mar is something over sixty miles. 5. Road from Santo Domingo to Higuey. This road is the same as the Sabana la Mar road as far as Guerra, then traverses small forests and grassy plains to Seibo, passing through the important towns of Los Llanos and Hato Mayor. The greater part of the last 36 miles of the road, from Seibo to Higuey, runs over the foothills of the central mountain range. The entire length of the road is about 110 miles.
