INTRODUCTION

To the use of the Terrestrial Globe.

Q. What is the Terrestrial Globe?

A. It is a round body representing the earth, with all its divisions marked out as on the map of the world, and is used in the study of geography.

What is the Axis of the earth ?* What are the Poles? What is the Equator? What are Great Circles? What are Less Circles? What are Meridians? Into how many degrees ís every meridian divided? How is each degree divided? Into sixty equal parts called minutes. How is each minute divided? Into sixty equal parts called seconds.

Q. How many horizons are there?
A. Two; sensible and real.

Q. What is the Sensible Horizon?

A. It is the line where the earth and sky seem to meet.

Q What is the Real Horizon?

A. It is a great circle which divides the earth into upper and ower hemispheres.

Q. How is the horizon divided?

A. Into four equal parts of 90° each.

f

Q. What is the Wooden Horizon ?

A. It is a wooden circular frame on which the globe rests. Q. What is the Brazen Meridian?

A. It is the circle of brass in which the globe turns, and is divided into 360 equal parts.

What are zones ?* How many are there, and what are their names? Describe the limits of each? How many seasons has the Torrid Zone ? How many have the Temperate Zones ? How many the Frigid? What is Latitude? What is Longi

tude? Are degrees of longitude equal in length? What is the greatest latitude a place can have? What is the greatest longitude? Where has a place no longitude?

meridian do most nations reckon longitude ?†

Q. What is the Ecliptic?

From what

A. It is an imaginary great circle in the heavens which the earth describes in its annual revolution round the sun.

Q. How is this marked on the globe?

A. Obliquely to the equator, making with it, an angle of 23° 28!.

Q. How is the ecliptic divided?

A. Into 12 equal parts of 30° each, corresponding to the 12 signs of the Zodiac.

Q. What is the Zodiac ?

A. It is a broad belt in the heavens, 16° wide, through the centre of which the ecliptic is drawn.

Q. How many Colures are there, and what are they?

A. Two; one is the meridian which passes through the equinoctial points, called the equinoctial colure; the other is the meridian which passes through the solstitial points, called the solstitial colure.

Q. Where are the equinoctial points?

A. Where the ecliptic cuts the equator.

Q. Where are the solstitial points?
A. Where it touches the tropics.

Q. Why are they called equinoctial points?

A. Because when the sun reaches these points, the days and nights are equa!.

Q. Why are the other points called solstitial?

A. Because the sun here appears to stand still, i. e., it neither approaches the north or the south.

Q. When does the sun reach the equinoctial points?

A. March 21st, and September 23d.

Q. When does it reach the solstitial points?

A. June 21st, and December 22d.

Q. What is the Quadrant of altitude?

A. It is a thin strip of brass divided into 90°, used to determine the distance between any two places.

Q. What is the Hour Circle?

A. It is a small circle drawn round each pole, on which the hours of the day are marked. A movable index is attached to

each pole, pointing to the figures in the hour circle.

Q. How many degrees at the equator, does each hour indi

cate?

A. Fifteen.

PROBLEMS.

1. TO FIND THE LATITUDE OF ANY PLACE.

Turn the given place to the brass meridian, and the degree directly over it indicates the latitude required.

What is the latitude of Halifax ? Boston? Liverpool? Cape Horn? London? Constantinople? Naples? San Francisco? Calcutta? The mouth of the Amazon? Cairo? Edinburgh? Paris? New-York?

2. TO FIND THE LONGITUDE OF ANY PLACE.

Turn the given place to the brass meridian, and the degree on the equator under the meridian, shows the longitude required.

What is the longitude of Moscow? Cairo? Philadelphia? Lisbon? St. Petersburg? New-Orleans? Amsterdam? Quebec? Tunis? Dublin? Madias? Aleppo? Boston? Batavia? Athens? New-York?

3. TO FIND ALL THE PLACES ON THE GLOBE THAT HAVE THE SAME LATITUDE WITH ANY GIVEN PLACE.

Turn the globe, and all places passing under the latitude of the given place, will be those required.

What places on the globe, have 51% degrees north latitude? What places have 16 degrees south? What places have the same, or nearly the same latitude with Stockholm? NewOrleans? Philadelphia ?

4. TO FIND ALL THE PLACES ON THE GLOBE THAT HAVE THE SAME LONGITUDE WITH ANY GIVEN PLACE.

Turn any place to the brass meridian, and all the places under the same edge, have the same longitude.

What places have the same longitude with London? Dantzic? Boston? Portland? Vienna ? Lima? Stockholm? What places have no longitude?

5. TO FIND ALL THOSE PLACES THAT HAVE THE SAME HOUR AT THE SAME TIME.

All places situated under the same meridian from the Arctic to

the Antarctic Circle, have the same hour at the same time.

What places have noon at the same hour with New-York? Washington? Vienna? St. Louis ?

When it is sunrise at Charleston, what time is it at the Isthmus of Darien? When it is noon at Alexandria, at what places is it midnight? When it is sunset at Vienna, at what places is it sunrise? When it is midnight at New-Orleans, at what places is it noon-day?

6. THE LATITUDE AND LONGITUDE BEING GIVEN, TO FIND THE

PLACE.

Turn the given degree of longitude to the brass meridian, and under the given degree of latitude, will be the place required.
