plying the perimeter of the base by the alti- 

 tude. 



The volume of a prism is found by multiply- 

 ing the area of the base by the altitude. 



Problems. 1. What is the entire surface of a

prism whose base is 2 inches square and whose 



altitude is 6 inches? 



Lateral area in sq. in.= (4 X2) X6 = 48 

 Area of bases in sq. in. = 2x (2x2) =8 

 Entire surface in sq. in. = 56 



2. What is the volume of a triangular prism 

 20 inches high, whose base is a right triangle 



with a base of 12 inches and an altitude of 8 

 inches? 



Area of base in sq. ln. = 12x%=4S 



Volume in cu. in. = 48x20 = 960 



3. What is the volume of a prism whose 

 altitude is 15 feet and whose base is a regular 

 hexagon 2 feet on each side? 



Solution: (1) See base as a regular hexagon 

 divided into six equal triangles. (2) Draw alti- 

 tude of one of these triangles, dividing the tri- 

 angle into two right triangles. (3) We have base 

 and hypotenuse of right triangle, to find altitude. 

 ( 4 ) Base = 1 ft. 



Hypotenuse = 2 ft.

4. What is the lateral area of a silo built 

 in the shape of a hexagonal prism 30 feet high, 

 each side of the base being 6 feet 8 inches long? 



Lateral area in sq. ft.= (6x6%) X 30 = 1200.

RISON , priz'n. The word prison reached its 

 English form through the Latin and the French 

 languages. Originally it meant to lay hold of, 

 or to seize; a prison, therefore, was any place 

 where persons were held in safe custody after 

 arrest. There was no distinction between jails 

 and penitentiary. To-day a jail is a purely 

 local institution, maintained for the temporary 

 safe-keeping of a person accused of crime un- 



is guilt or innocence is established, and as 

 a place of imprisonment for those convicted 

 of petty offenses who arc sentenced to a few 

 days' or a few months' detention. 



A prison, or penitentiary, is not a town, city 

 or county institution, but is a part of the ma- 

 chinery of government of a state or province. 

 It is not a place for detention of petty offend- 

 ers or youthful criminals, but for the imprison- 

 ment of adults, both male and female, who 

 have been found guilty of serious offenses 



against society and who have been sentenced 

 for periods varying from one year to the re- 

 mainder of their lives. In jails short-term 

 prisoners are maintained in idleness; in prisons 

 labor is provided, and each inmate works at a 

 productive task, under strict discipline. 



Management. Every state prison is in im- 

 mediate charge of a warden, who nearly always 

 receives his appointment from the chief execu- 

 tive of the state or province; in a few instances 

 a board of prison control assumes this respon- 

 sibility. Until within recent years wardens 

 were appointed largely as rewards for political 

 activity, regardless of fitness ; this rule yet holds 

 in some parts of America, but the awakening 

 consciousness of the people is bringing about 

 a notable reform. Fewer incompetent wardens 

 are now in charge of prisons than ever before; 

 men who have made prisons a subject of long 

 study are being placed in these important posts,
