The*flowers spring in great spikes from the cen ter of t he crown of leaves a nd are arranged in whorl-like clusters along t he spike, t he female flower occupying t he base of t he spike and t he male t he apex. T he aver age weight of a b u n ch is about 25 lbs., b ut they a re often known to exceed 70 or 80 lbs. In t he greenhouse Cavendishii, two years ago, t he dwarf banana, M. matured a b u n ch of fruit t h at weighed 65 lbs. The productive power of t he banana is prodigous. On an acre of land it was estimated by H u m b o lt t h at it would produce 44 times as m u ch in weight as t he pota to, and 133 times as much as wheat. T he banana is in many other ways useful to m a n. The stem yields a juice t h at is used as an astringent and its spongy pith, when pounded a nd boiled, forms a nutritious food of a starchy character. All parts of t he plant abound in fibre t h at is adapted to t he manufacture of cordage and paper though it has never been utilized to any great extent. T he top of t he stem is boiled and eaten as a vegetable and t he leaves are used in pickling and for many domes tic purposes. Greenhouse. NARROW ESCAPE EROM DROWNING. One day during t he recent cold snap Mr. Steele, who has for several years been an employe on t he horticul tural department, having occasion to cross t he river into t he college woods east of No. 7, went across on t he ice. This was in t he morning. After working in t he woods all day he returned just at dark, took a light pole in h is h a n ds and started to recross t he ice. B ut during t he day t he ice h ad softened, and t he current, which is here very swift, had c ut t he ice away underneath until only a thin shell remained, and when near t he middle of t he stream Mr. Steele suddenly found himself plunged arm-pit deep into t he swift, cold current. He called repeatedly for help, b ut being nearly half a mile from t he nearest house, could make no one hear. He t h en began breaking his way to shore b ut here a new danger presented. time he attempted to break t he ice ahead of him his feet would be lifted from t he bottom a nd he was in imminent danger of being swept under t he ice. T h a n ks to t he pole which he h ad k e pt in his hands, he was able to brace himself against t he current and slowly break t he ice from in front until he got to where t he water was shallower when he made more rapid progress. After being in t he water about half an hour he at last reached t he shore and t h en rapidly made his way to his home about half a mile distant, where a good fire and dry clothing soon restored his normal temperature. Every THE MONEY VALUE OF MARL. Schoolcraft, Mich., March 2, 1896. DEAR S I R —I send you by mail a sample of shell marl. W h at do you think of it to use as a fertilizer? Can be delivered here at $4.30 a ton. T h o u g ht it might help me to get a stand of clover. Yours truly. W. F. C. The marl was examined and found to be a very p u re less t h an one half of one per cent of marl, containing sand and a small amount of vegetable matter. T he money value of marl consists mainly in t he amount of lime it contains. Carbonate of lime contains 56 per cent of lime (CaO), and 44 per cent of carbonic acid. We cannot afford to pay cash for carbonic acid for man ure, as it is found abundantly in t he air and wind h as no money value. If t he marl were pure, a ton would contain 1,120 pounds of lime, or 16 bushels. T he question whether t he farmer can afford to pay $4.30 for 16 bushels of lime depends on t he further question whether he can buy t he lime cheaper. An agent of theBellevue Lime Co., of Bellevue, E a t on Co., gave me to understand t h at they would sell lime, free on board cars at Bellevue, in car load lots at t en cents a bushel. At this rate t he ton of marl would be worth $1.60. Caustic lime is more active t h an carbon ated lime, and on certain soils (mucky) would give more marked results. Caustic lime is soon changed to car bonate of lime by absorbing carbonic acid from t he air. Marl is a b u n d a nt in many p a r ts of this state, and where it can be obtained for no expense beyond t he cost of handling it, t he marl is a cheap and valuable m a n u r e, b ut its money value is not large.

Mr. Apted, who is having t he trouble, is a hustler in business a nd some t i me ago he conceived t he idea of utilizing one of their m a m m o th old caves, from which t he plaster h as been mined, for mushroom growing. Consent of t he stock company was obtained under certain restrictions, and Mr. Apted commenced over a year ago to t ry his skill. t ip to a month or two ago prospects were very flatter give him acre ing. A seventeen possibilities of a nd an occasional treat for Chicago besides. T he temperature, too, does not vary summer or winter and is just right to t he degree for raising mushrooms t he year r o u n d. These are two of t he most essential conditions at t he start and success seemed imminent, when, all unexpectedly, there came this mighty scourge of little mites; too small to be detected individually by t he unaided eye, b ut in legions sufficient to injure or destroy every mushroom before it is old enough for market. Most of t he mushrooms are being destroyed while in t he young or pin-point stage. In some beds where t he mushrooms were not very plentiful, t he mites would g a t h er in large mass meetings, awaiting t he arrival of In t he larger stools t h at pin-points t h r o u gh t he crust. had escaped at first t he mites were burying them selves in groups here and there over t he cap. t he mite Such was t he condition of affairs on my arrival. W h e t h er we will win the day or yield to this little invader remains for t he future to decide. T he cave is very dry, and in such an atmosphere thrives and breeds rapidly. If we could create a h u m id atmos phere like t he florist can in fighting t he red spider, t he question would be solved, b ut t he stock company say t h at industry h as m u st n ot be, even though t he mushroom to be given up, as it will rot the supports and disinte grate t he plaster rock above. Mr. Apted h as already tried all t he remedies t h at Grand Rapids people have suggested to him, which is no small n u m b e r, with only negative results in t he main. We shall t ry several methods not yet definitely tested and with fair pros pects t h at at least one of t h em will succeed. If we are successful in banishing t he mites, there still remain several species of insects, one of which, a maggot, is quite a serious pest. It bores devious chan nels through t he inner part of t he mushroom in a way very m u ch like t he radish and cabbage maggot does in those plants. I have searched entomological literature for information regarding them a nd t he other insects, and have written t he department at Washington, D. C, b ut without success, a nd I think t he field will prove to be a very interesting one for study and experimental work. Zoological Department. T HE BANANA. T H OM AS GUNSON. The two varieties of bananas, each bearing a b u n ch of fruit, attract alike t he attention of students a nd t he visiting public in t he greenhouse at present. As t he banana is truly t he fruit of the laboring classes and can be bought so cheaply nearly every day in t he year, it is not surprising t h at people like to see a plant growing in something like its natural condition. It is amusing to hear t he comments some people make on seeing t he banana plant in fruit for t he first time, and to note how vastly superior t he plant is to any preconceived idea they may have formed of its general appearance. The banana is one of t he aristocrats of t he vegetable kingdom, a nd while it h as long been t he principal far inaceous food of t he people of nearly all tropical and semi-tropical countries, it is only within recent years t h at its fruit has been used to any extent by people of colder climates. Though really herbs, bananas assume all t he appear ances of trees. Their stems, consisting of t he sheath ing bases of t he stalks of t he large palm like leaves, are soft, spongy a nd destitute of wooden structure, yet some species attain a height of twenty-five feet. T he stems die after perfecting t he fruit, and fresh stems are developed from buds in t he root-stock, which is peren nial. These stems are t he common sources from which t he plant is propagated for making fresh plantations, and t he growth is so rapid t h at in t he West Indian islands, where conditions are favorable, t he fruit is us ually ripe within ten months of t he time of planting t he In t he greenhouse with t he best t r e a t m e nt we offsets. can give t h em it takes t he plant more t h an twice t h at length of time to do t he same amount of work.
