The grade of instruction in these subjects is in accordance 
with the abihty and attainments of the students. Students tak- 
ing any subjects by correspondence shall be not less than 15 
years of age and shall not at the time of taking the course be in 
attendance at school. 
Instruction in the subjects mentioned is given by written les- 
sons or assignments, the student returning a written report on 
each lesson or assignment according to the direction of the pro- 
fessor in charge. These reports are carefully examined and re- 
turned to the student with such corrections, explanations or sug- 
gestions as may be to the interests of the student. If each re- 
port meets the required standard, a new lesson or assignment is 
sent. 
A subject consists of weekly assignments and each assignment 
may contain one or more lessons. The course of instruction 
terminates with the close of schools in June. No preliminary 
examination is required, but students must satisfy those in charge 
of the course that they can read and write English fluently. Ap- 
plication blanks may be had on request and the College will of- 
fer assistance and suggestion in the choice of subjects. Students 
are expected to complete at least one course in the time specified 
for the course. 
A fee of $5 is charged for each full course of 18 assignments. 
For additional courses a reduction of one-half for each course 
is made. The fee is intended to pay the cost of the lessons c:nd 
postage one way. If a student takes less than half of the assign- 
ments one-half the fee remaining above the cost of materials used 
is refunded. 
SUBJECTS IN DETAIL. 
Course 1. Soils and Crops: Readings and reports on the 
origin and formation of soils, their physical, chemical and bio- 
logical properties, relation of soil properties to soil managements, 
the adaptation of crops to soil types, and the essentials of crop- 
producing power. The studies of crops will consist of read- 
ings and reports on the leading crops of the mainland and Ha- 
waii, their geography, economics of production, commercial im- 
portance, products, uses and culture methods. 
Course 2. Plant Life: Students registering in this course 
have an option between two lines of study. 1. A survey of the 
principles of botany, including the structure and physiology of 
the seed plants ; the morphology, evolution, and classification of 
plants ; ecology and economic botany. The text by Bergen and 
Davis will be furnished. Emphasis will be laid on the practical 
phases of plant-life, especially such aspects as are exemplified 
in Hawaii, and in similar tropical regions. 2. A study of com- 
mon plants as an aid in the nature-study work of the elementary 
schools. This work is planned primarily for school-teachers.
