_Circular_, having the form of a circle, round. By whom was it built? By Agrippa, the Consul of Rome, twenty-five years before Christ; it was dedicated by him to Jupiter: the name Pantheon was given on account of the great number of statues of the Gods ranged in niches all round it; and because it was built in a circular form to represent heaven, the residence of the Gods. It was afterwards converted into a church by Pope Boniface IV, and dedicated to the Blessed Virgin and all the Martyrs, under the title of "Our Lady of the Rotunda." Agrippa likewise built the Pantheon at Athens, which was but little inferior to that of Rome. The Greek Christians afterwards converted it into a church, dedicating it to the Blessed Virgin; but the Turks, when they subdued Greece, changed it into a mosque. _Dedicated_, appropriated to a particular person, or to a sacred use. _Residence_, dwelling, habitation. _Martyr_, one who is put to death for the cause of religion. _Mosque_, a Mahommedan temple. [Illustration: A SLATE QUARRY.] What is understood by a Consul? The chief magistrate of the Roman republic or commonwealth. After the Romans had expelled their kings, they were governed by two Consuls; these were established in the year of Rome 245. The Consuls were the head of the senate; they commanded the armies of the republic, and judged all the differences between the citizens: they held their office for the space of a year; at the end of which time, new ones were elected. Consuls were even continued under the Emperors after the republic was destroyed; but it was then little more than an honorary title, and at last was totally abolished. _Expelled_, turned out. _Abolished_, annulled, made void. To what is the term Consul applied at the present time? To an officer established by a commission from a king or state, to reside in foreign countries of any considerable trade, to facilitate and despatch business, protect the merchants of the state, &c. _Commission_, a trust imposed, command, authority. _Facilitate_, to render easy. What is meant by a Senate? An assembly or council of senators, that is, of the principal inhabitants of a state, who have a share in the government. What is the government of the United States? It is one of limited and definite powers, defined by a written constitution. How are the legislative powers, granted to the government, vested? In a Congress, consisting of a Senate of two Senators from each state, chosen by the legislature thereof; and a House of Representatives, consisting of one or more members from each state, elected by the people in equal electoral districts. _Legislative_, giving or enacting laws How are our laws made? Bills passed by the House of Representatives and the Senate, on receiving the sanction of the President, become laws; or, if vetoed by the President, may be passed by two-thirds of both Houses.
