THE INDIGENEOUS TREES 
OF THE HAWAIIAN ISLANDS 
By J. F. Rock 
Charles E. Tuttle Co., Rutland, 
Vermont, 1974 548 pp., 
215 photographic plates 
First published in 1913, this vol- 
ume has now been reprinted by 
popular demand. In view of the 
considerable changes wrought in 
the Hawaiian Islands by popula- 
tion and building pressures, the 
Pacific Tropical Botanical Gardens 
with offices in Kauai has assumed 
the responsibility for this fine new 
edition. The environment of the 
islands was largely undisturbed 
over six decades ago when Rock 
first explored the area with his 
crude photographic equipment. It 
was his belief that a _ botanist 
should record unusual plants with 
a camera as well as a notebook. 
Like most island plant species, 
the native forests of Hawaii are 
very fragile and many plants 
known in Rock’s time no longer 
exist. The seeds of its native trees 
arrived by wind currents, ocean 
currents and by fruit-eating shore 
birds in long-distance flights of mi- 
gration. Rock classifies the botani- 
cal regions into six areas, among 
them the lower forest, the middle 
forest and the bog region. He des- 
cribes many trees in great detail,

ENERGY FOR SURVIVAL 
By Wilson Clark 
Anchor Press—Doubleday and Co., 
Inc., New York, 1975, $4.95 
In this book, Clark points out our 
mistakes of the past and our pres- 
ent energy policies and emphasizes 
corrections that need to be made. 
Much of the book is directed 
toward alternate sources of energy 
that need to be developed. 
Clark reviews Barry Commoner’s 
basic laws of ecology as guidelines 
in our conservation and use of en- 
ergy and then proceeds to give 
some measures toward conserving 
energy use. 
Some alternate promising sources 
of energy that need to be developed 
are the sun’s radiation, wind pow- 
er, tidal energy, geothermal heat, 
electrolysis of water, energy from 
farm crops, trees, waste compost- 
ing, sewage farming. 
Some of these suggested alterna- 
tives are now being seriously re- 
searched and developed. All con- 
servation-minded people need to 
be informed and use as many al- 
ternate sources as possible if our 
present world is to continue.

BLUEBIRD PROJECT UNDERTAKEN STATEWIDE 
To better understand and improve the status of Eastern Bluebirds 
in Illinois, Michael Morrison, P.O. Box 2503, Carbondale, 62901, 
has volunteered to coordinate and assemble all data for this 
species. In order to do this, he needs cooperation from all persons 
who maintain Bluebird Trails and keep no‘es on Bluebird nests. He 
particularly requests information about abundance and distribution 
of Bluebirds throughout all of Illinois, nesting and hatching success 
in all areas, the types of boxes or natural cavities used, etc. By 
combining all statewide results and publishing an annual report, 
we will stimulate more interest in bluebirds and assist the nesting 
population. If you have past copies of reports, Mr. Morrison would 
appreciate receiving them. Your complete cooperation is re- 
quested. Please note his address as printed above.
