write a language with accuracy, agreeably to reason and correct usage.

Rhetorick teaches us to speak copiously and fluently on any subject, not merely with propriety alone, but with all the advantages of force and elegance; wisely contriving to captivate the hearer by strength of argument and beauty of expression, whether it be to entreat and exhort, to admonish or applaud.

Logick teaches us to guide our reason discretionally, in the general knowledge of things, and directs our enquiries after truth. It consists of a regular train of argument, whence we infer, deduce, and conclude, according to certain premises laid down, admitted, or granted; and in it are employed the faculties of conceiving, judg ing, reasoning, and disposing; all of which are naturally led on from one gradation to another, till the point in question is finally determined.

Arithmetick teaches the powers and properties of numbers, which is vari-ously effected, by letters, tables, figures, and instruments. By this art, reasons and demonstrations are given, for finding out any certain number, whose relation or affinity to another is already known or discovered.

Geometry treats of the powers and properties of magnitudes in general, where length, breadth, and thickness, are considered, from a point to a line, from a line to a superficies and from a superficies to a solid.

A point is a dimensionless figure; or an indivisible part of space.

A line is a point continued, and a figure of one capacity, namely, length.

A superficies is a figure of two dimensions, namely, length and breadth.

A solid is a figure of three dimensions, namely, length, breadth, and thickness.

The advantages of Geometry. By this science the architect is enabled to construct his plans, and execute his designs; the general to arrange his soldiers; the engineer to mark out ground for encampments; the geographer to give us the dimensions of the world, and all things therein contained, to delineate the extent of seas, and specify the divisions of empires, kingdoms, and provinces; by it, also, the astronomer is enabled to make his observations, and to fix the duration of times and seasons, years and cycles. In fine, geometry is the foundation of architecture, and the root of the mathe

maticks.)

Musick teaches the art of forming concords, so as to compose delightful harmony, by a mathematical and proportional arrangement of acute, grave, and mixed sounds. This art, by a series of experiments, is reduced to a demonstrative science, with respect to tones, and the intervals of sound. It enquires into the nature of concords and discords, and enables us to find

out the proportion between them by numbers.

Astronomy is that divine art, by which we are taught to read the wis dom, strength, and beauty of the Almighty Creator, in those sacred pages, the celestial hemisphere. Assisted by astronomy, we can observe the mo tions, measure the distances, comprehend the magnitudes, and calculate the periods and eclipses of the heavenly bodies. By it we learn the use of the globes, the system of the world, and the preliminary law of nature, While we are employed in the study of this science, we must perceive unparalleled instances of wisdom and goodness, and, through the whole creation, trace the glorious Author by his works.

The moral advantages of geometry. This is the first and noblest of sciences; it is the basis on which the super-structure of Masonry is erected. By geometry we may curiously trace nature, through her various windings,

By

to her most concealed recesses. it we discover the power, wisdom, and the goodness, of the Grand Artificer of the Universe, and view with delight, the proportions which connect this vast machine. By it we discover how the planets move in their different orbits, and demonstrate their various revolutions. By it we account for the return of seasons, and the variety of scenes which each season displays to the discerning eye. Numberless worlds are around us, all framed by the same Divine Artist, which roll through the vast expanse, and are all conducted by the same unerring law of nature.

A survey of nature, and the observation of her beautiful proportions, first determined man to imitate the divine plan, and study symmetry and order. This gave rise to societies, and birth to every useful art. The Archi tect began to design, and the plans which he laid down, being improved by experience and time, have produced works which are the admiration of eve ry age.
