greatest agricultural development may be expected in future. (See 
figs. 11 and 12.) Agricultural production is permanently limited 
to this region on the east by Uruguay and the Atlantic Ocean; on 
the south and west by semiarid conditions; on the north by a sub- 
tropical climate — a portion of which is subhumid — less fertile soils, 
belts of timber and marsh, more numerous insect pests, lack of 
population and schools, and other primitive pioneer conditions. 
Mainly for this reason the statistics oi agricultural production have 
been limited in the past to the five or six principal agricultural 
Provinces. 
Cereals 
The following statistics (Tables 27 to 32 inclusive) relate (1) to 
the Republic as a whole, (2) to the five principal Provinces of the 
cereal region, and (3) to the most important crops grown in other 
regions. It should be understood that the statistics here given are 
largely estimates, although some of them are labeled "Census;" 
but they are the best obtainable and are believed to be sufficiently 
accurate for use as index numbers :

Oats, barley, and rye are generally sown in the fall for pasture during the winter months. The area 
harvested depends entirely upon conditions the following spring. Very little alfalfa is cut for hay. Aver- 
age production figures are lacking for other crops prior to 1924. The last item "Other crops and planted 
trees" refers especially to orchards and considerable areas planted to forest trees for shade, shelter, and 
fuel.
