- At the thirty-sixth annual meeting of the Association of Officers of Colleges in New England, held at Williams College, Nov. 3-5, 1892, it was voted that the following memorandum be furnished to all educational journals for publication, but with the declaration that this action of the association does not commit any college faculty to the recommendations made in the memorandum: The Association of Officers of Colleges in New England, impressed with the real unity of interest and the need of mutual sympathy and help throughout the different grades of public education, invites the attention of the public to the following changes which, without insisting upon details, it recommends for gradual adoption in the programme of New England gratamar schools. Art. 1. The introduction of elementary natural history into the earlier years of the programme as a substantial subject, to be taught by demonstrations and practical exercises rather than from books. 2. The introduction of elementary physics into the later years of the programme as a substantial subject, to be taught by the experimental or laboratory method, and to include exact weighing and measuring by the pupils themselves. 3. The introduction of elementary algebra at an age not later than twelve years. 4. The introduction of elementary plane geometry at an age not later than thirteen years. 5. The offering of opportunity to study French, or German, or Latin, or any two of tbese languages from and after the age of ten years. 6. The increase of attention in all class-room exercises in every study to the correct and facile use of the English language. In order to make room in the programme for these new subjects, the association recommends that the time allotted to arithmetic, geography, and English grammar be reduced to whatever extent may be necessary. The association makes these recommendations in the in. terest of the public school system as a whole; but most of them are offered more particularly in the interest of those children whose education is not to be continued beyond the grammar school.

– An interesting experiment in naturalization, namely, tbe transfer of living lobsters (Homarus vulgaris) from England to New Zealand, has just been crowned with success. Tbe fitting-up of steamers with refrigerating chambers for the carriage of frozen meat from New Zealand to the Mother Country, has enabled experiments to be carried out, with every prospect of success,

which were formerly considered almost impossible of fulfilment. Some years ago humble-bees were by this means successfully carried to the island colony, where they have increased amazingly, and from whence they have since been carried to Australia and Tasmania. Shipments of salmon ova are likewise now made almost without loss. The latest experiment, the carrying out of live lobsters, has also been successfully accomplished. This result is due to Mr. Purvis, chief engineer of the steamship “ Ionic,” who has taken great interest throughout in this work. An attempt was made last year by the same gentleman, at the nce of the Otago Acclimatization Society, who were aided in their efforts by Mr. John Ewing of London and Dr. Cunningham of the Plymouth Biological Station. The attempt, however, failed almost at the outset. Tanks were constructed on board the steamer, and stocked with lobsters, but within a few days after starting all the crustaceans died. The construction of the tanks was probably faulty. On the last outward trip of the steamer, Mr. Ewing obtained a

dozen tine specimens of lobsters, and handed them over to Mr. Purvis, who safely conveyed nine of them to their destination. These animals, four males and five females, were liberated on a rock-built mole at the entrance to Otago Harbor, where they are likely to thrive, and from whence they will no doubt spread widely. The coast-line, both north and south, is rocky, and is eminently suited for crustaceans. At present it is tenanted by a large crayfish (Palinurus), and it will be an interesting problem to see how the introduced animal will thrive. The crayfish is strongly armed defensively with a strong carapace and stout spiny prominences on its front, and on the anterior limbs. It is extremely common on the coast. But there are no crustaceans with the formidable chelæ of the lobster, and it will most probably be able to more than hold its own. This first shipment is certain to be followed by others, and it is almost safe to predict that in a few years frozen lobsters will form one of the articles of export from New Zealand.

SKETCH OF THE FLORA OF DEATH VALLEY, CALI

FORNIA.

2

BY FREDERICK VERNON COVILLE, WASHINGTON, D.C. SINCE Death Valley, as shown by the published records of the Weather Bureau,’ is the hottest and drvest area known in the United States, and probably in the world, and since the observations of the Death Valley Expedition showed that these extreme climatic conditions are reflected in its vegetable life, a description of this flora has an interest even greater than that incited by the average desert vegetation.

One not familiar with the Mohare and Colorado deserts must imagine broad stretches of treeless plains, out of which rise abrupt mountains, not covered with trees but exbibiting naked faces of rugged rocks with no covering of soil or lichens to conceal even their coloration. In the northern portion of the Mohave Desert region, in which Death Valley lies, the mountain ranges are closer together and the plain is cut up into narrow deep valleys trending in a general north and south direction. The deepest of these is Death Valley, its length about 175 miles, and its greatest breadtb from peak to peak about 20 miles. The lowest portion of the valley is a moist plain about 40 miles Jong by 2 to 6 miles broad, gleaming with salt and alkali.

this nd the mountain faces are sloping gravelly mesas, at some parts of the valley 6 miles broad, at other points entirely absent. The mountains themselves are abrupt and naked, the Funeral Mountains on the east rising 7,000 feet, the Panamints on the west almost 11,000. Upon the crest of the Panamint range is an evergreen forest of pines and junipers.

The salt-flat in the bottom of the valley is quite devoid of vegetation, not because the moisture in the soil is too scant, but because it is so saturated with salt and alkaline compounds that no plant can live upon it.

The mesa bears a growth of scattered shrubs pot sufficient, even at a distance, to conceal the ground between them. No larger plant is to be seen except at certain points where, along the line between the mesa and the salt-flat, the sub-soil is sufficiently moist to support the mesquite. This is a low, almost shrub-like, tree which commonly attains a height of 10 to 15 feet. This characteristic then, the absence of trees, may be taken as the most conspicuous feature of the Death Valley vegetation, as it is of the desert in general.

The mesas bear, besides the shrubs, a large number of berbaceois plants which, although in late summer and in winter dead and barely noticeable, in the spring months of a rainy year come to be in some places really conspicuous. One of the desert sunflowers (Encelia eriocephala) was at one point so abundant that it even made the mesa appear yellow, at a distance, orer an area many rods in extent. The general impression, however, of the traveller who is not a botanist is that the vegetation of the valley consists of clumps of mesquite set here and there along the edge of the salt flat, and a few scattered greasewood and creosote bushes on the mesa.

Not all parts of the mesa are, however, supplied with even so much plant life. At the mouth of Furnace Creek Cañon is a broad slope composed of mixed gravel, sand, and clay, a matrix capable, in some parts of the desert, of supporting a varied flora; but bere for hundreds of yards is seen no plant whatever except one of the smallest greasewoods (Atriplex hymenelytra), its individuals growing far apart and attaining the height of barely a foot.

In still other portions of the mesa occurred a phenomenon which, if it is here interpreted rightly, is tbe best index that we have of the intense heat of this region. The higher portions of the mesa are cut up by the dry channels of the streams that follow mountain cloudbursts. Between these channels, which are called sometimes arroyas but oftener washes, are broad blocks of the mesa, whose surface has lain undisturbed for undoubtedly many thousands of years. The surface of the soil is covered closely with a layer of small, flat, water-worn stones which have accumulated on the top of the ground by the gradual washing out of their original clayey matrix. The erosion of the soil has undoubtedly been brought about by the slow agency of direct rainfall. The upper surfaces of the stones have a dark brown, almost black, color, and the dull lustre of a hard-burned brick. The coloration of these stones is ascribed to binoxide of manganese, produced by oxidation due to intense light acting during long periods of times. These so-called sunburned areas in Death Valley bear no vegetation whatever. Even the two desert annuals, Chorizanthe rigida and Chænactis attenuata, which grow at other points in the hottest spots, are here wanting. The soil, a firm clayey one, is good, and the surface receives just as much rainfall as other parts of the valley. The phenomenon is explained by no hypothesis except that of intense heat, and a consideration of the evidence, in the absence of direct experiment, indicates that such a cause may be quite sufficient.

Experiments by Sachs upon active protoplasm have shown that when subjected to a temperature of 50° C. (122° F.) it ceases to carry on its functions, disintegration sets in, and death follows. But a plant may be situated in an atmosphere whose temperature is higher than this without itself attaining so great a beat; for two causes tend to reduce its temperature, the non-conductive nature of the tissues themselves, and the evaporation that characterizes transpiration. Yet even these sources of protection may be overridden by a still higher temperature. The well-known retention of vitality in the case of the spores of certain fungi after exposure to a temperature of even 212° F. does not indicate that a desert plant cap endure a similar degree, for the protoplasm of the fungus spore is not in a state of activity, but that of a germinating or growing plant is.

The Weather Bureau tables, in the bulletin cited above, show five records of a temperature of 122° F. This is the temperature of air sheltered from the effects of radiation. The temperature of air exposed to ordinary conditions of radiation must be somewhat higher than this, and the temperature of gravel pebbles on the surface of the ground still higher; but, according to the principles of molecular pbysics, the black stones that have been described should reach a degree of heat decidedly greater than either of the other bodies. It is confidently believed that a temperature of from 140° to 150° F. is frequently attained under these conditions, and in such a temperature a growing plant would undoubtedly perish from beat.

That the flora of the valley may be more readily considered, all the species observed there have been arranged in groups.

A review of these groups suggests some of the leading characteristics

1 In January, 1891, an expedition was sent out by the U. S. Department of Agriculture to explore the region of Death Valley, California, and to make a biological survey of it. About nine months were spent in the field, and the report, now nearly completed, will soon be publishod by the department. The general botanical features of the region, a full discussion of which will constitute a part of the final report, are here described by the botanist of the expedition.
