a) Construct the same light lines as in stage a, b, c, d, of the previous lesson until we get the lines shown above.
b) This time we firm in the 'diagonals' which become railway line 'sleepers'. Notice here we use a more simplified method of construction.
c) Keep adding sleepers.
d) After the student has completed the drawing to the stage above ask: What shall we call the line that joins LVP, RVP and CVP? (answer 'horizon line'). How wide are railway tracks? (remember the old movies of people tied to railway lines? - answer about 5feet). If the distance between the sleepers is 5 feet what is the distance between the second add fourth sleepers?
e) Add the extra light lines on the ground (two horizontal and three to the CVP). We are going to build a station about 30mm (1,1/4") from track 60mm wide.
f) Add the vertical lines 50mm (2") high and join to CVP
g) Firm in the lines as shown and ask:
How high is the building? The student should measure the
width of the tracks on the line directly opposite the
front edge of the station and apply that 'scale' to the
Objects an equal distance away from the 'observer' are subject to the same measurements of 'scale ' at that distance.
In this drawing the scale is discovered by knowing the width of the track at that distance.
h) Add the telegraph lines and poles and have the student determine their height and distance apart.
Clean up and print in the title as shown.
Encourage the advanced students to add three 12 foot cacti at various locations in the landscape.
Complete the drawing adding a roof on the station, cactus, hills , train, and birds etc.
