PREFACE 

This Flora of the Pacific States has been made to enable 
pupils to obtain a clear idea of the method of classifying 
plants through practical experience in identifying the most 
common genera and species of the coast. It is to serve as a 
guide in understanding the characteristics and relationships 
of large and important orders and genera, and, to some 
extent, in identifying species. 

The species included have been those most widely dis- 
tributed or those most abundant near large centers of popula- 
f^^on, so that sufficient material might easily be obtained for 
^ class study. Species not clearly and easily defined have been 
^ omitted even when abundant, so as to render the possibility 
t of error as little as possible. Where a difference of opinion 
? exists among botanists in regard to generic names, both have 
fe<r^ generally been given, one in parentheses, 
f Teachers will find, in whatever part of the Pacific States 
^ they may be, that they can collect a sufficient number of the 
'^ plants here included to afford their pupils all the drill neces- 
iPsary. It is advised that the teachers furnish the plants for 
H? class study, being careful to select only from those here 
^ included rather than to allow the pupils themselves to select 
at random from the flora of the neighborhood ; otherwise, the 
^ pupil is likely to become discouraged by failure in identifying 
plants not described in the book. 



'A PREFACE 

Teachers who are in doubt about any plants are earnestly 
requested to send specimens to the Academy of Sciences, San 
Francisco, where they will be compared with herbarium speci- 
mens and identified. The specimens should have both flower 
and fruit when possible, and in the case of herbs the entire 
plant should be sent, root and all. 

It requires quite a library of botanical books to identify 
Pacific Coast species, since there is no book published that 
contains even all the known species, and there are many 
species still undiscovered. It is neither possible nor desirable 
to attempt to include all in a school flora. The chief books 
needed for a more complete study are the two large and 
expensive volumes of the State Geological Survey ; the fol- 
lowing botanical works of Prof. E. L. Greene : Plttonia, Flora 
Frcuiciscana, and The Botany of the Bay Region ; Western 
Cone-hearers, by J. G. Lemmon ; and, for Com2)ositcB and 
Ganioiyetake, Gray's Synoxjtical Flora. 

The plan of arrangement in preparing this Flora has been 
that of Professor Bergen's Key and Flora to the Spring- 
hlooming Flants of the Northern and Middle States, which 
replaces this in the Eastern edition of his book. It seemed 
that a plan which he had tried and found successful was 
better to adopt than one that was new and untried. When- 
ever possible, his descriptions have been used, the aim 
throughout having been to follow as he led. 

The botany of the Geological Survey, Professor Greene's 
botanical works, and Dr. Behr's Botany of the Vicinity of San 
Francisco have all been used in compiling the descriptions 
and making the Key. 



PKEFACE 3 

The figures referred to are to be found in the text of this 
Key, unless the reference is preceded by/, or e. The former 
refers to Bergen's Foundations of Botany, the latter to his 
Elements of Botany. 

The pronunciation is indicated by accent marks and the 
division of the accented syllable. A vowel ending this 
syllable has a long sound ; but when the accented syllable 
ends in a consonant, the vowel has a short sound. It 
matters little whether the English or Continental sounds 
for the vowels are used ; the former are more generally 
authorized, though the latter are becoming more and more 
prevalent. 

In this revised edition I am indebted to Prof. C. ^ . Piper, 
of the Agricultural College, at Pullman, Washington, for 
additions to the Flora from Washington and Oregon, and 
to Mr. Louis A. Greata, of Los Angeles, for additions from 
the country adjacent to Los Angeles.

CLASS I. — GYM'NOSPERMS 

Plants destitute of a closed ovary, style, or stigma ; ovules 
generally borne naked on a carpellary scale, which forms part 
of a cone. Cotyledons often several. 

CONIF'ER^. Pine Family 

Trees or shrubs with wood of peculiar structure, destitute 
of ducts, with resinous and aromatic juice. Leaves generally 
evergreen and needle-shaped or scale-shaped. Flowers desti- 
tute of floral envelopes, monoecious or dioecious. Male flowers 
consisting of stamens arranged in a spike, and ■ resembling a 
catkin, with pollen sacs at the base of scales, subtended by a 
cluster of bracts like an involucre. Female flowers consisting 
of naked ovules at the base of scales arranged in a spike with 
a cluster of bracts below, in fruit forming a cone with the 
seeds under the scales or becoming a one- to few-seeded berry. 

I. JUNIP'ERUS, Jumper, Cedar 

Flowers dioecious, axillary or terminal. Staminate clusters 
numerous, with scales whoiied or opposite, on a central axis, 
and 2-6 anther cells to each scale. Pistillate clusters of 
3-6 fleshy scales, each bearing 1-2 erect ovules. Fruit a 
herry. Seeds bony. Shrubs or low trees, usually branching 
irregularly, with aromatic wood and thin, shreddy bark. 
Leaves either triangular, scale-like, folding over each other, 
or linear, rigid, pointed, and free from each other. 

II. CUPRES'SUS, Cypress 

Monoecious. Staminate clusters small, very numerous, and 
at the tips of tiny branchlets ; pollen sacs 3-5 at the base 
of each scale. Fertile clusters erect on short lateral branchlets, 

13 



14 KEY AND FLORA 

forming, when ripe, roundish or oblong woody cones, con- 
sisting of 6-10 very thick, shield-shaped scales, fitting closely 
together ; cones maturing in two years in all except the last ; 
ovLiles numerous, in several rows at the base of the scales, 
forming acutely angled seeds. Leaves evergreen, scale- 
shaped, imbricated. When the tree is allowed to grow 
naturally, it is pyramidal, or roundish, with rather loose, 
straggling branches and pointed or rounded at the top. In 
bloom in winter or early spring. 

a. C. macrocarpa Hartweg. Monterey Cypress. This has 

dense foliage and oblong cones clustered on short stems. It is 
extensively cultivated throughout CaHfornia for wind breaks and 
hedges; also trimmed into the most fantastic shapes, which are 
supposed to be ornamental. 

b. C. Govenia'na Gordon. Mountain Cypress. This is a more 
loosely branched and smaller tree, with the upper branches slender 
and drooping. The cones are an inch or less long, and are globose, 
rarely oblong. This, too, is cultivated. In its native state it grows 
throughout the Coast Mountains. 

c. C. Macnabia'na Murr. Tliis is a small tree with fine foliage very 
fragrant, sprinkled all orer ivith irhite glands, so that the tree is pale 
green. The cones are small, ic'th horn-like projections on the scales. 
This also is cultivated, but rarely. It is a native of the mountains 
of Lake County. 

d. C. Lawsonia'na Murr (Chamaecy'paris). Port Orford Cedar. 
This differs from the other species of Cupressus in having flattened, 
2-ranked branches, and the cones ripening in one year. Cones very 
small, ^ of an inch in diameter, globose, with 8 or 10 flat scales which 
are bluish green when j^oung. Seeds 2-4 to each scale, somewhat 
winged. This is a tall, symmetrical tree with slender branches, 
often drooping. It is frequently cultivated and is a very valuable 
timber tree. The wood is very fragrant and is used in making chests 
and cupboards where it is desirable to keep out insects. It is also 
known as Oregon Cedar and Ginger I^ine. It is found chiefly in the 
Coast Mountains of Oregon. 



III. THU'YA, Arbor-vitae 

Monoecious. Staminate flowers numerous, very small, with 
3 or 4 pollen sacs at the base of the 4-6 pointed scales. 
Fertile clusters at the ends of branchlets. Cones very small, 
■^ inch long, soon reflexed, ripening in one year, with 8-12 erect 



GYMNOSPERMS 15 

scales in ^^airs, having a pair of ivinged seeds under all except 
the top and bottom pair. These are tall, symmetrical trees, with 
horizontally flattened branches and scale-shaped, evergreen 
leaves adnate and decurrent in 4 rows, with the tips free. 

T. gigante'a Nutt. This is a very tall tree found in the Coast 
Mountains of Oregon, in Washington, northern Idaho, and British 
Columbia. The cones are densely clustered at the ends of the droop- 
ing branchlets, and the foliage is a bright, shining green. The bark 
is thin and fibrous, the wood soft but durable. 



IV. LIBOCE'DRUS, Incense Cedar 

Similar to Thuya, but with 12 or more scales on tfie stami- 
nate cluster and tvith the cones not reflexed. These consist of 
Jf.-6 thick scales in pairs, the two largest only bearing seeds. 
Seeds with unequal wings. 

L. decur'rens Torrey. This becomes a large tree in the Sierra 
Nevada Mountains and has a trunk resembling that of the giant 
Sequoia. It is also found on almost all the higher hills of the 
Coast Mountains. 

V. SEQUOrA, Redwood 

Monoecious. Staminate flowers small, very numerous near 
the ends of young shoots, with 3-5 pollen sacs under each 
scale. Fertile flowers at the ends of branchlets, consisting of 
several scales with longpointed tips which become bristles on 
the shield-shaped scales of the cone. Each scale is diamond- 
shaped tvith lines running to the center, giving the cone a 
quilted appearance. The Sequoias are the largest trees on 
earth. Their leaves are flattened or triangular scale-shaped ; 
the bark very thick, fibrous, and spongy ; the wood red and 
soft, easily split longitudinally, and the bark also cleaving 
longitudinally. Both species are cultivated in different parts 
of California. 



a. 



S. semper'virens Endl. Redwood. Cones small, oblong, of 
about 20 scales, maturing in one season ; lower leaves flat, 2-ranked ; 
upper leaves, on tall trees, scale-shaped. This forms immense forests 
in northern Cahfornia and extends, along the coast, from southern 
Oregon to Point Gorda in Monterey County. The specific name 



16 KEY AND FLORA 

arises from its tenacity of life. It sends up new trees in a circle 
around where a tree has been cut down. In bloom in winter. 

b. S. gigante'a Decaisne. Mammoth Sequoia, Big Tree. 
Upper and lower leaves alike, scale-shaped, ivith long-pointed tips ; 
cones about 2 in. long of 25-30 scales, requiring two seasons to 
ripen. This is found in groves in moist, protected valleys in the 
higher Sierras, from Placer County through Tulare County. 

VI. A'BIES, Fix 

Tall trees tapering from a rather broad base to a pointed 
top, with horizontal branches and brittle wood that soon 
decays. Leaves apparently in 2 ranks, generally erect, 
twisted at base. Cones erect, near the top of the tree, the scales 
and seeds falling away from the axes, which remain like 
candles on a Christmas tree. The cones are therefore never 
found under the trees, only the fallen scales. 

a. A. con'color Lindl. White Fir. Large trees with old bark 
rough, gray, and furrowed. Leaves pale green, obtuse. Cones 3-5 
in. long, green or purple when ripe. This is the common fir 
of middle elevations in the Sierra Nevada Mountains. It also 
extends into Oregon. 

b. A. gran'dis Lindl. Tall and large trees with smooth, brownish 
bark. Leaves dark green and glossy on the upper surface, with 2 
white lines on the lower, obtuse or notched at apex. Cones 2-4 in. 
long. This is probably the tallest fir in the world. It is found 
near the coast from northern California to British Columbia and is 
one of the most important sources of lumber. 

Vn. PrCEA, Spruce 

Tall trees, shaped as the firs, and with soft but strong 
wood. Leaves sessile, spirally arranged, falling from the 
branchlets as soon as dry and leaving the stems covered with 
numerous tiny projections, sometimes appearing in 2 ranks. 
Cones drooping, growing on the upper branches, falling to the 
ground when ripe and always to he found under the hearing trees 
with the scales spirally arranged on the axes. 

a. P. Sitchen'sis Carr. Tideland Spruce. Very tall and large 
trees with thin, scaly, brownish red bark. Leaves slender, sessile, 
with short points at the apex. Cones 1^-3 in. long, yellowish. 



GYMNOSPERMS 17 

This is one of the most important trees of the northern Pacific 
coast and is probably the largest spruce in the world. It extends 
from northern California to Alaska. 

h. P. Engelman'ni Engelm. Engelmann Spruce, White Spruce. 
Bark light cinnamon-red, broken into thin loose scales. Young 
trees of pp-amidal outline ; old trees in forests with long straight 
trunks and pyramidal at top. Leaves stiff, ending in a sharp tip. 
Branchlets pubescent. Cones cylindrical, about 2 in. long. Wood 
white, valuable as timber. This replaces the preceding species east 
of the Cascade Mountains. 



Vm. TSU'GA, Hemlock Spruce 

Similar to the true spruces but with flatter leaves, having 
short petioles joined to a hard, woody, persistent base. Seeds 
resinous on the surface and cones smaller. Tall trees of 
pyramidal outline and slender, drooping branchlets. 

a. T. heterophylla Sargent. Bark thick, reddish brown. Cones 
less than an inch long, ovate. This is found along the coast from 
northern California to Alaska and is one of the most important 
timber trees. 

h. T. Mertensia'na Sargent (T. Pattonia'na). Patton's Spruce, 
Hemlock Spruce. Trees with thick, cracked bark, reddish gray 
and apt to be scaly. Cones long and slender, 2-3 inches in length. 
Seeds with wings almost twice their length. This is shrubby at 
great elevations, but when favorably situated becomes a tree more 
than a hundred feet high. The apex is slender and pendent and the 
trunk generally slopes at base. It is found in the higher Sierra 
Nevada Mountains and northw^ard to Alaska, wdiere it grows along 
the coast. 

IX. PSEUDOTSU'GA, Douglas Spruce 

Flowers monoecious, from the axils of last year's leaves. 
Staminate clusters subtended by conspicuous involucres of 
bud scales ; pollen scales with 2 oblong pollen sacs tipped 
by an awl-shaped spur. Fertile clusters near the ends of 
branchlets, dark red or yellowish green, with scales concealed 
by 2-lobed, long, pointed bracts. Cones oblong, drooping, 
maturing in one year, but remaining on the trees after the 
seeds have fallen out. The leaves are flat and 2-ranked, on short 
petioles. This can easily be distinguished from other conifers 
by the fringe-like bracts over the scales of the drooping cone. 



18 KEY AND FLORA 

P. mucrona'ta Sudw. (P. Douglas'ii Carr), (incorrectly called 
Oregon Pine and Red Fir). This is found in California and 
Oregon, and usually grows near streams. It becomes a very tall 
tree. The wood is yellow or reddish and rather coarse, and the bark 
is fissured. 

X. PFNUS, Pine 

Monoecious. Staminate clusters crowded at the base of the 
young shoots of the season ; pollen scales spirally arranged, 
forming an elongated, cylindrical cluster, with 2 pollen sacs 
to each scale (Fig. 1, 2). Fertile flowers of spirally arranged 
carpel scales on an axis, each scale bearing 2 ovules at base 
(Fig. \, 3). Fruit a cone ripening the second year, but often 
remaining unopened on the tree several years. Leaves ever- 
green, needle-shaped, in bundles of from 2-5, enclosed in a 
sheath of membranous scales (Fig. 1, d). Seeds generally 
winged (Fig. 1, 4). 

a. P. Lambertia'na Dougl. Sugar Pine. Leaves 5 in a sheath, 
3-4 in. long. Cones long, narrow, cylindrical, from a foot to more 
than 2 ft. long when fully grown, pendent at the ends of the branches 
the second year, the scales ivithout knobs or prickles. This is a very tall 
and large pine, with the upper branches widely spreading and with 
irregular and picturesque outlines. It is common in the Sierra 
Nevada Mountains at moderately high elevations and on most of 
the high peaks of the Coast Mountains, extending into Washington 
and Oregon. 

b. P. montic'ola Dougl. Small Sugar Pine. This is a smaller 
tree than the preceding but similar, with leaves 5 in a sheath, about 
2 in. long. Cones 3-8 in. long, with the scales without knobs or 
prickles, reflexed when the seeds are ripe. This is common in the 
higher Sierra Nevada Mountains, especially northward, and extends 
into Oregon and Washington at lower elevations. 

c. P. pondero'sa Dougl. Yellow Pine, Leaves 3 in a sheath, 
5-11 in. long, rather thick. Cones oval, 3-5 in. long, sessile, spread- 
ing or recurved, generally several together ; scales with stout prickles. 
Wings on the seeds not quite an inch long, widest above the middle. 
This is one of the largest pines of the coast. It is found in the 
mountains in the same region as the Sugar Pine but more widely 
distributed. The variety Jeffrey! is found generally at higher eleva- 
tions and has longer, coarser leaves, and much larger cones.. This 
is the most widely distributed species and one of the most prized 
timber trees.

slender, straight stems by the Indians. It is w^idely distributed and 
variable. 



20 KEY AND FLORA 



e. P. radia'ta Don (P. insig'nis Dougl.). Monterey Pine. Leaves 
3 in a sheath, 4-6 in. long, slender, lax, closely serrate, bright green, 
densely clustered. Cones encircling the stein, dejiexed on short stems, 
pointed, curved inwards, owing to the difference beticeen the inner and 
outer scales. The cones remain on the tree two or more years without 
opening. This pine is most extensively cultivated in California for 
wind-breaks. It grows nearly 100 ft. in height. 

/. P. attenua'ta Lemmon (P. tubercula'ta Gord.). Knob-cone Pine. 
Leaves 3 in a sheath, 4-7 in. long. Cones in ichorls, often with several 
whorls in a hunch, strongly refiexed on short stems, oblique, tapering to 
a very narrow base, with the apex pointed ; the outer scales are 
enlarged and conical, the inner flatter, both tipped with stout prickles. 
The cones persist on the stems and branches many years without 
opening. This is a small tree and often begins to bear cones when 
a foot or two high. It is found in the Coast Mountains and in the 
foothills of the Sierra Nevada Mountains. 

g. P. Sabinia'na Dougl. Xut Pine, Bull Pine, Digger Pine. 
Leaves 3 in a sheath, 8-12 in. long, light glaucous green, slender, droop- 
ing : cones massive, short-oval, 6-10 in. long, 5-7 in. in diameter 
near the base, deflexed on short, stout stems ; scales with stout, claw-like 
projections. The nuts are edible and have a stony shell, and formed 
an important part of the food of the Digger Indians. This tree 
generally has loose spreading branches and is very graceful. The 
long light-green foliage easily distinguishes it from other pines. The 
cones often remain on the branches several years after the seeds have 
fallen out. This pine is the most common in the foothills of the 
Sierra Nevada Mountains and in the valleys of the Coast Mountains.

CYPERA'CE^. Sp:dge Family 

Grass-like or rush-like herbs, with solid, usually triangular 
stems, growing in tufts. The sheathing base of the generally 
3-ranked leaves, when present, is not slit as in grasses. The 



MONOCOTYLEDONOUS PLANTS ' 23, 

flowers are usually somewhat less enclosed by bracts than 
those of grasses ; the perianth is absent or rudimentary ; 
stamens generally 3 ; style 2-cleft or 3-cleft. 

The flower cluster and the flower may be understood from 
an inspection of Fig. 4. 

The species are even more difficult to determine than those 
of grasses. 

ARA'CE^. Arum Family

from a thick rootstock. Spadix at first covered by a yellow- 
ish green spathe, later extending beyond it on a stout 
peduncle. Flowers covering the spadix. Stamens 4, oppo- 
site the segments of the perianth, with 2-celled anthers 
opening upwards. 

L. Kamtschatcen'sis Schott. This is found in swamps from 
northern California to Alaska. It blooms in May and June. It is 
a beautiful plant with large, broad leaves, covering the swamps, but 
it has a strong and disagreeable odor, from which the common 
name is derived. 



LILIA'CE^. Lily Family 

Herbs. Flowers regular and symmetrical, with their parts 
3 or some multiple of 3. Ovary 3-celled, free from the 
perianth. Fruit a capsule or berry. Seeds with endosperm

rotate, or funnel-form. Stamens in 2 sets, 3 or 6, attached to 
the tube of the perianth, often with wing-like appendages on 
the filaments ; when 3, alternating with petal-like staminodia. 
(Staminodia are filaments, usually broadened, without anthers.) 

(There are 5 subgenera which Professor Greene regards 
as genera; so, to avoid confusion, the species are arranged 
under the subgenera.) 



26 kp:y and flora

Legumes mmierous, more or less 2-celled by one or both sutures 
projecting inwards, often inflated like a bladder so as to secure 
disjjersion of the seed by the luhid. Several species are poison- 
ous to cattle and sheep. Almost all are perennials. The 
species are numerous and too difficult for beginners.

MYRTAXE^, Myrtle Family 

Eucalyp'tus. There are many different species of this 
genus cultivated in California. The young shoots have oppo- 
site leaves much broader than the older leaves, which are 
alternate. The calyx never opens. It is like a lid and falls 
off. Under this is another very thin lid which answers to 
the corolla. Then the numerous stamens rise and expand, 
producing a tassel-like blossom. The fruit is a 3-5-celled 
capsule imbedded in the receptacle and opening by chinks at 
the top. The commonest species in cultivation is the Blue 
Gum, Eucalyptus globulus Labill.

BERGEN'S ELEMENTS OF BOTANY 



By JOSEPH Y. BERGEN, 

Instructor in Biology in the English High School, Boston. 



i2mo. Cloth. 332 pages. Fully illustrated. 
For introduction, $1.10. 



Mr. Bergen's book differs from most other botanies of 
similar grade in the following details : 

In carrying through a simple account of the gross struc- 
ture, the microscopical structure, and the functions of the 
several parts of the plant side by side. 

In paying special attention to Vegetable Physiology and 
illustrating the subject by many simple experiments. 

In choosing for the experimental part of the work such 
experiments as may, if necessary, be carried on in the 
schoolroom during the regular recitation period. 

In employing for study largely such materials as are 
readily obtainable everywhere and at all seasons. 

In offering abundant pictorial illustrations, chosen from a 
very wide range among the most authentic sources. 



John M. Coulter, Head Professor of 
Botany, University of Chicago : I have 
been recommending Bergen's Elements 
of Botany to the teachers of the public 
schools as a very useful book. It con- 
tains the flavor of modern botany, retains 
much of the old that is useful, is simple, 
and enforces the necessity of laboratory 
and field work. 

W. W. Rowlee, Assistatit Professor 
of Botany, Cornell University, Ithaca, 
N. Y. : Comes nearer to outlining an ideal 
course for high schools than any book I 
have seen. 

W. F. Ganong, Professor of Botany, 
Smith College, Northampto^t, Mass. : 
The book comes fully up to our expecta- 
tions. I shall make use of it with my 
elementary classes. 



Thomas J. Burrill, Professor of Bot- 
any, University of Illinois, Urba7ia, III. : 
When asked to recommend a botanical 
text-book for use in the high school, I un- 
hesitatingly name Bergen's Botany. 

W. Q. Tight, Professor of Geology 
and Natural History, Denison Univer- 
sity, Granville, Ohio : After a term's use 
of Bergen's Botany, I find it fulfills all 
my expectations. The most practical 
text-book on botany offered to our high 
schools and academies. 

Geo. G. Groff, Professor of Organic 
Sciences, Buc knell University, Lewis- 
burg, Pa. : An excellent work. I have 
taken pleasure in commending it to the 
teachers in our school.

Williams' Laboratory Manual of General Chemistry is still kept in stock. 
For introduction, 25 cents. 



The Elements of Chemistry is very fully and carefully illus- 
trated with entirely new designs, embodying many original 
ideas, and there is a wealth of practical experiments. 
Exercises and problems follow the discussion of laws and 
principles. 

The subject-matter is so divided that the book can be 
used by advanced schools, or by elementary ones in which 
the time allotted to chemistry is short. 

Chemical Experiments is for the use of students in the 
chemical laboratory. It contains more than one hundred 
sets of the choicest illustrative experiments, about half of 
which belong to general chemistry, the rest to metal and 
acid analysis. 

The Laboratory Manual contains one hundred sets of ex- 
periments in inorganic general chemistry, including brief 
treatment of qualitative analysis of both metals and non- 
metals, and a few quantitative experiments.

TEXT-BOOKS ON PHYSICS 

By ALFRED P. GAGE,

Principles of Physics. A text-book for high schools and colleges. 
i2mo. Half leather. 634 pages. Fully illustrated. For intro- 
duction, $1.30.

244 pages. Illustrated. For introduction, 35 cents. 

Physical Experiments. A Manual and Note Book. 8vo. Boards. 
195 pages. Illustrated. For introduction, 35 cents. 



The Principles of Physics aims to supply the demand for an 
accurate, interesting, usable text-book of present-day physics, 
suitable for high schools and elementary courses in college. 

The size and general features of the Introduction to Physical 
Science in its present revised form have been changed little, 
but numerous slight changes have been made throughout 
the work which will be found improvements and which will 
make it more acceptable to those using it. 

In general plan the revised Elements of Physics is similar 
to the original book, though distinctly less inductive. Many 
improvements in method of presentation have been intro- 
duced as a result of the author's experience as a teacher 
and a text-book maker. Recent advances in the industrial 
applications of physical principles receive due attention. 
The department of mechanics is given full treatment, and a 
large number of problems and practical exercises is furnished 
throughout the book. 

Physical Experiments contains the laboratory exercises 
required for admission to Harvard University and to many 
other colleges.

A Series of text-books on astronomy for higher schools, 
academies, and colleges. Prepared by one of the most dis- 
tinguished astronomers of the world, a most popular lecturer, 
and a most successful teacher. 

The Lessons in Astronomy was prepared for schools that 
desire a brief course free from mathematics. The book has 
just been revised and brought fully up to date. Great pains 
has been taken not to sacrifice accuracy and truth to brevity, 
and no less to bring everything thoroughly up to the present 
time. 

The Elements of Astronomy is a text-book for advanced high 
schools, seminaries, and brief courses in colleges generally. 
Special attention has been paid to making all statements 
correct and accurate. 

The eminence of Professor Young as an original investi- 
gator in astronomy, a lecturer and writer on the subject, 
and an instructor in college classes, led the publishers to 
present the General Astronomy with the highest confidence ; 
and this confidence has been fully justified by the event. 
It is conceded to be the best astronomical text-book of its 
grade. The present edition has just been thoroughly revised 
and enlarged.
