SPECIAL REPORT Rare earths a r e becoming less rare under AEC's sponsorship of thorium extraction from monazite and its need for individual rare earths as well. Companies foresee de­velopment of larger commercial outlets. Page 550.

FEATURE Film replaces a technical paper to present a labora­tory technique. Authors tell how it's done. Page 627.

L E T T E R S Controversy still rages over Strauss suggestion to ease science teacher shortage by recruiting practicing chemists and engineers. Page 541.

I N D U S T R Y Spending fo r construction of new chemical plants should reach $2.3 billion by end of 1957, MCA survey reveals. Total for 1955 was $772 million, while an additional $1.6 billion -was committed. Page 553.

Hercules plans expenditures for 1956 almost double those of 1955. Only obstacle: steel delays. Page 555.

RESEARCH Cyanamid gives research coordinate status with its nine operating divisions. I t is consolidating all research formerly scattered in its Calco, Lederle, and Stamford opera­tions into its new research division. Page 556.

Research on detergents in s e w a g e will s tar t with ÂBS types since they account for over 40% of the 2 billion pounds made annually. Soap & Glycerine Producers is sponsoring a multi-pronged program. Page 558.

G O V E R N M E N T Better enforcement of food and drug la»*-s is ahead as new government budget allots Food and Drug i-ministration $1 million more than last year. Increase will put more inspectors on the payroll. Page 562.

MANAGEMENT Cyanamid updates its trade-mark to make it encompass all company products. Page 566.

E D U C A T I O N National Science Foundation's $1 million awards launch summer institutes and experimental programs for high school science teachers. Page 572.

PEOPLE "Recognition of shortcomings in existing products and research to improve them constitute the best kind of commercial development," says Don Ballman, CCDA Award winner. Page 578.

I N T E R N ATlON A L Russian work done in 1880 seems to dem­onstrate priority in discovery of vitamins. Eugen Wierbicki of OSU says this is nationalistic propaganda. Page 589.

A S S O C I A T I O N S ACS and AlChE local sect ions cooperate in eighth annual Delaware Chemical Symposium in Newark, Feb. 18. The 32-paper program will be divided into six sessions: analytical, organic, physical, and polymer chemistry; general and chemical engineering. Page 595.

How often have you thought, "If I

could have one extra man for a week,"

or "If I could have 100 extra men for

a day." What a perfect way to meet a

•deadline!

Long ago we realized that labora­

tory executives were having wishful

thoughts like these. That ' s why we

established the kind of organization

^ve now have —to make available man­

power and facilities unlimited for ap­

plication to the emergency needs of

industry.

Today, when you must face the

worst technical manpower shortage in

history, this service becomes more

important to you than ever before.

Within our organization you will

find the man you need — whether he

be an experienced scientist or a skilled

technician. What is even more impor­

tant — you buy just enough of his

services to do the job you want — no

more and no less.

If you're faced with a problem that

calls for some extra technical man­

power or facilities — call us today. An

inquiry imposes no obligation.

How Much of

OUR TIME Do You Need?

That sprinkler system may be frozen solid, even though it's only carrying compressed air This happened five years ago— Fire inspectors in St. Louis tested the spr inkler

system in a cold storage plant and found it useless.

Moisture in the compressed air that fills the pip­

ing to prevent jreezeups had condensed and frozen

at points where supply lines enter the cold rooms.

Water couldn't ge t past this ice.

Booth Cold Storage Company, also of St. Louis, became alarmed at this report and tested their sprinkler system. T h e same condition ex is ted — frozen supply lines and no sprinkler protection. So they took immediate steps to clear their lines

and made certain this never happens again.

derivatives hold more promise for process and product

improvement than any chemical family developed in

the past twenty-five years. Learn how the NP's may
