Crops ; 458, Best Two Sweet Sorghums for Forage ; 477, Sorghum

Exercise 26. — A Study of Types and Varieties of Sorghums. 
Purpose: To familiarize students with a class of field crops some 
of which may prove of great value to local agriculture. 
Directions : The school should have a fairly complete collection of 
the types and varieties of sorghums as heads and thrashed material. 
The collection and mounting of varieties grown locally should be 
assigned to students. The collection may be completed by purchase, 
or by exchange w T ith other southern schools, of material from firms 
which supply agricultural laboratories. The varieties of sorghum 
may be grouped under the following heads: (1) Saccharine, in- 
cluding the varieties used for sirup; (2) nonsaccharine, or grain sor- 
ghums, including kafir, milo, and other durras, and such miscella- 
neous varieties as the kaolings, shallu, and darso; and (3) broom 
corn. 
The following outline may be used in the description of each 
variety: (1) Head; length, circumference, and shape; (2) seed; 
size, shape, color, hardness; and (3) glumes; hairy or smooth, color, 
length. 
If score cards are not obtainable from the State agricultural col- 
lege or State department of agriculture, the class should make up 
score cards for judging both head samples and grain samples. Prac- 
tice in judging may follow according to the time available and in 
accordance with the importance of the crop. 
Note. — If the sorghums are not adapted to the section in which the school 
is located, the same study may be made of some other group of forage crops 
which is little known and which may give promise, such as the millets. 
Lesson 18. — Sugar Cane. 
Lesson 27. — A Study of Sirup Making. 
Purpose: To familiarize students with modern methods in making 
cane sirup. 
Directions : The class should visit a farm or factory where the 
most modern methods are in vogue. The teacher should make ar- 
rangements before the visit so that the time may be spent most 
profitably in a study of the processes from the grinding of the cane 
to the canning of the sirup.
