 in all the states; it collects and disseminates general information regarding agricultural schools, colleges, stations, and publishes accounts of agricultural investigations at home and abroad; it also indicates lines of inquiry for the stations, aids in the conduct of co-operative experiments, reports upon their expenditures and work, and in general furnishes them with such advice and assistance as will best promote the purposes for which they were established; it conducts investigations relative to irrigation and drainage; (14) the office of public roads, which collects information concerning systems of road management, conducts investigations regarding the best method of road-making, and prepares publications on this subject.

In the following countries there are state departments of agriculture:—Argentina, Belgium, Brazil, (industry, agriculture and public works), Bulgaria (commerce and agriculture), Denmark, France, Norway (agriculture and public accounts), Italy, Japan (agriculture and commerce), Prussia (agriculture, woods and forests), Russia (agriculture and crown domains), Sweden.

AGRIGENTUM (Gr.  mod.  (q.v.)), an ancient city on the south coast of Sicily, 2 m. from the sea. It was founded (perhaps on the site of an early Sicanian settlement) by colonists from Gela about 582, and, though the lastest city of importance founded by the Greeks in Sicily, soon acquired a position second to that of Syracuse alone, owing to its favourable situation for trade with Carthage and to the fertility of its territory. Pindar (Pyth. xii. 2) calls it . The buildings for which it is famous all belong to the first two centuries of its existence. Phalaris, who is said to have roasted his enemies to death in a brazen bull (Pindar, Pyth. i. 184), ruled as tyrant from 570 to 554. What form of government was established after his fall is uncertain; we know only that, after a long interval, Theron became tyrant (488–473); but his son Thrasydaeus was expelled after an unsuccessful war with Hiero in 472 and a democracy established. In the struggle between Syracuse and Athens (415–413) the city remained absolutely neutral. Its prosperity continued to increase (its population is given at over 200,000) until in 405, despite the help of the Siceliot cities, it was captured and plundered by the Carthaginians, a blow from which it never entirely recovered. It was colonized by Timoleon in 338 with settlers from Velia in Lucania, and in the time of the tyrant Phintias (289–279) it had regained some of its power. In the First Punic War, however, it was sacked by the Romans (261) and the Carthaginians (255), and finally in the Second Punic War by the Romans (210). But it still retained its importance as a trading and agricultural centre, even in the Roman period, exporting not only agricultural products but textile fabrics and sulphur. In the local museum are tiles used for stamping cakes of sulphur, which show that the mines, at any rate from the 3rd century, were imperial property leased to contractors.

The site is one of great natural strength and remarkable beauty, though quite unlike that of other Greek cities in Sicily. The northern portion of it consists of a lofty ridge with two summits, the westernmost of which is occupied by the modern town (985 ft.), while the easternmost, which is slightly higher, bears the name of Rock of Athena, owing to its identification in modern days with the acropolis of Acragas as described by Polybius, who places upon it the temple of Zeus Atabyrius (the erection of which was attributed to the half mythical Phalaris) and that of Athena. It must be confessed that the available space (about 70 × 20 yds.) on the eastern summit (where there are some remains of ancient buildings) is so small that there would be only room for a single temple, which must have been occupied by the two deities jointly, if the new theory is correct (see Notizie degli scavi, 1902, 387 and reff.). In the modern town, on the other hand, the remains of one temple are to be seen in the church of S. Maria dei Greci, while the other is generally supposed to have occupied the site of the cathedral, though no traces of it are visible. But whichever of these two summits was the acropolis proper, it is certain that both were included in the circuit of the city walls. On the north both summits are defended by cliffs; on the south the ground slopes away somewhat abruptly from the eastern summit towards the plateau on which the town stood, while the western summit is separated from this plateau by a valley traversed by a branch of the Hypsas [mod. Drago], the deep ravine of which forms the western boundary and defence of the city. On the east of the city is the valley of the Acragas [Fiume S. Biagio], from which the city took its name and which, though shallower than that of the Hypsas, still affords a sufficient obstacle to attack, and the two unite a little way to the south of the town; at the mouth was the ancient harbour, small and now abandoned.

The most famous remains of the ancient city are the temples, the most important of which form a row along the low cliffs at the south end of the city. All are built in the Doric style, of the local porous stone, which is of a warm red brown colour, full of fossil shells and easily corroded when exposed to the air. It should be noted that their traditional names, with the exception of that of Zeus and that of Asclepius, have no foundation in fact, while the attribution of the temple in antis, into the cella of which the church of S. Biagio has been built, is uncertain. They are described in R. Koldewey and O. Puchstein, Die griechischen Tempel in Unteritalien und Sicilien (Berlin, 1899), 138-184. Of all these temples the oldest is probably that of Heracles, while the best preserved are those of Hera and Concordia, which are very similar in dimensions; the latter, indeed,
