The 1914 Census has less complete details in regard to interior immigration than its predecessor. The migrations had not ceased. The attraction of Tucuman and Mendoza had, in fact, decreased. The province of Tucuman had 55,000 Argentine immigrants, the province of Jujuy 15,000, the province of Mendoza 34,000. The provinces of Mendoza and Corrientes remained nuclei of considerable immigration (38,000 and 63,000 immigrants). At Santa Fe the number of emigrants who left the province to settle at Cordoba and in the remainder of the Pampean region rose from 14,000 to 87,000. The Patagonian territory also had a large excess of immigrants from other provinces. Periodic migrations with no definitive change of residence are not given in the official statistics. The importance of these migrations in northern Argentina has been noted in the chapters we devoted to Tucuman and the forestry industry. They occur also in the Pampean region, where they are due chiefly to the need of labour for the harvest and the threshing of wheat and flax, and for reaping the maize. Miatello has given us a detailed analysis of the phenomenon for the province of Santa Fe in 1904. The period when the wheat and flax growers need help is from November to February. It begins in March for the maize farmers, and lasts so much longer when the harvest is good. The temporary immigrants come partly from Europe. Not only is the stream of immigration to Argentina fuller during the months which precede the harvests, while the stream of re-emigration to Europe is greatest in the autumn, but it is not a rare thing for Italians to go every year to Argentina merely to stay there during the harvest, when wages are high. This seasonal immigration from Italy is of long standing; it is mentioned by Daireaux in 1889. These foreigners, however, are only part of the adventurous crowd enlisted for the harvests on the Pampean plain. Seasonal migration is everywhere a national practice. The labour employed in reaping the maize includes elements borrowed from the towns near the maize belt. But all the provinces round the Pampean region send their contingent of temporary immigrants. Some even come from the valley of the Rio Negro at Bahia Blanca, from San Luis, and even from Mendoza to the Central Pampa and the Cordoba province. The oldest, and still the largest, stream is that which comes from the Santiago province. D'Orbigny notices in 1827 the temporary streaming of Santiaguenos to the coast. In that year slow progress was made with the wheat-harvest of Buenos Aires because of the shortage of labour. "The forced levies for the army prevented the Santiaguenos from going to hire themselves, as was their custom, in fear lest they should be compelled to serve."[139] [139] D'Orbigny, _Voyage dans l'Amerique meridionale_, vol. i. p. 528.
