central C for Christ.

A more elaborate lesson, illustrating the parable of the Pharisee and Publican, and showing the characteristics of three kinds of prayer and their results, can be portrayed thus:

Another still is to write a part of the test and fill it up with the answers of the scholars, thus:

"At thy word I will:Repent.
Pray.
Believe
Love.
Obey.
Suffer."

A lesson on the Beggars that cried to Jesus, as found in Matt. xx. 30-34, may thus be placed:

What the beggars did:cried in distress.
cried with importunity.
cried with faith.
cried with humility.
What Jesus did:stood still.
asked what they wanted.
had compassion.
touched them.
Result:He healed them.
They followed him.

Map Drawing.—Palestine.

Another use for the blackboard in the Sunday-school is the drawing of maps and outlines of the location of sacred places. Teachers have found it difficult, however, if not impossible, to draw maps of the proper proportions and rightly to locate the places. The following simple plan, used by Ritter and Guyot, has been extensively used in our Sunday-school Conventions the last year or two, and found to be useful. It is called the "Relative Measurement" method. One line, say from A to B (see diagram on page 123), is taken as the unit of measurement. This line is 40 miles in length. Having drawn this line at the top or northern boundary of Palestine, next dot off five times forty miles south, and number it in proper proportions, 1, 2, 3, 4, 5. Then run three times forty miles west, and number 6, 7, and 8. Then draw a line from A, sloping to the figure 8, for the coast-line, and you have the general outline of Palestine. Then run another dotted line from A to 6, and you have the Jordan line. The River Jordan rises opposite 1. The Sea of Galilee lies opposite No. 2. The Dead Sea opposite 4 and 5. The principal mountains are designated as /\ H. for Hermon, etc. Cities by * and letters, as Jer. for Jerusalem, C. for Cæsarea, etc. (See table.)
