Sunlight Sash make winter 

 gardening a pleasure 



There is none of the back-breaking, patience-trying 

 drudgery of covering and uncovering the sash. No 



mats or boards or coverings of any kind are used- 



The double layer of glass takes the place of mats or boards 



Between the two layers is a % inch transparent blanket of dry, still 

 air-keeping in the lieat-keepir.g out the cold. This also permits the 

 plants to get all the light all the time which means that they will grow 

 faster and become hardier. Glass slips in and is held in place without 

 putty. Can't work loose. Easily replaced. 



Read what amateurs grew last season 

 Fresh lettuce ani radishes all winter. Cabbage, cauliflower, beet, 

 tomatoes, pepper, and sweet potatoe plants 

 to set out in the Spring. Violets all 

 winter, pansies in bloom in February or 

 March.

NOS LIGHTING FDCT 



Complete harmony between lighting 

 fixtures and the other features of a room 

 is imperative if the height of the decorators 

 art is to be achieved. 



In this connection the ideas embodied 

 in Enos Fixtures often go far toward solv- 

 ing perplexing questions 

 that confront the home 

 builder. 



Before making a final 

 decision with regard to 

 lighting fixtures write us. 

 We will refer you to our 

 nearest office where you 

 will find suggestions well 

 worth considering.

AN ACOUSTIC MICROSCOPE 



AS is well known, the Academy of Sci- 

 ences of A^ienna possesses a very 

 generous collection of phonograms. 

 The commission in charge of these archives 

 is now working zealously to increase to 

 the greatest degree attainable the series of 

 idioms and variations of dialects, and for 

 this purpose is preparing delegations to 

 all countries. The first of these will be 

 for Sweden and Nubia. The proposed rec- 

 ords, however, will not be made merely 

 for purposes of culture and of the history 

 of language; the commission has greatly 

 enlarged the field of work of the phono- 

 graph, and has made of the instrument an 

 indispensable inventory of acoustic science. 

 In this respect the phonograph serves as 

 an "acoustic microscope," so to speak, for 

 small sections of the records on the plate 

 are magnified a thousandfold, and so form 

 an invaluable comparative material for the 

 theory of the formation of soimd and 

 speech and noises. 



One of the latest results of investigation 

 in accordance with this method may be 

 mentioned as an instructive instance of the 

 importance of this kind of microscopical 

 study: who that has the finest aural per- 

 ception is able to decide whether the "A" 

 of human speech concurs acoustically with 

 the "A" sound, with its astonishing sim- 

 ilarity, which is uttered by the frog in its 

 croaking tone? Here the observer in the 

 absence of the aid of the phonograph is 

 restricted to his sensibility and is exposed 

 to subjective errors, and for this reason 

 such investigation must lack an exact basis. 

 But such tonal emission magnified a thou- 

 sandfold shows promptly that the "A" 

 sound of the frog is intermitted at brief 

 intervals, a fact which the human ear can- 

 not grasp under ordinary circumstances, 

 and that unlike the "A" of human speech 

 it is a tone of interruption. From this point 

 of view may be recognized also the keen 

 importance this method has for the exam- 

 ination of pathological disturbances of 

 speech, for instance, and for the differen- 

 tiation of dialects even to their smallest 

 details. 



IN all atomizers for perfumes, etc., which 

 are now in use the rubber bulb is de- 

 tached from the bottle, with which it 

 is connected by a tube of rubber or metal. 

 In consequence of this arrangement, the 

 apparatus is of ugly appearance and incon- 

 venient bulk. In a new atomizer the bulb 

 occupies a depression in the wall of the bot- 

 tle, to which it is securely attached, al- 

 though it can be easily removed and re- 

 placed by a new bulb, when it is worn out. 

 The whole forms a smooth, round instrtt- 

 ment, differing little in shape from an or- 

 dinary bottle, easily handled, and of grace- 

 ful appearance. All of the parts : bottle, 

 bulb, nozzle, and cleaning needle, are inter- 

 changeable and are sold separately. 



REFERRING to the recent article in 

 the Scientific American describ- 

 ing the damage done to trees and 

 shrubs in connection with the tarring of 

 the driveway of the Bois de Boulogne in 

 Paris, a correspondent informs us that the 

 authorities in Sioux City have recently dis- 

 continued the use of tar on the park drive- 

 ways because of the damage done to grass, 

 shrubs, and trees adjoining the tarred sur- 

 faces. Another correspondent has recently 

 drawn attention to the fact that injury of 

 this character probably results from care- 

 lessness in the appHcation of the hot tar, 

 the fumes from which are destructive to 

 vegetable life.
