AMERICAN HOMES AND GARDENS 



October, 1910 



The carriage room, the stable, and the garage are ar- 

 ranged in a convenient manner and are thoroughly equipped 

 with all the best modern appliances. 



One of the most important features in the development 

 of an estate is the proper planning and arrangement of the 

 house and outbuildings upon a site. 



an attractive feature of the whole general scheme. 



In the planning of the house it was found desirable to 

 place all the living rooms so that they might have an ex- 

 posure, with an abundance of sunshine, in some part of 

 the house during the entire day, beginning with the dining- 

 room in the early morning and ending in the house to the

The ground plan, showing the relation of the house to the stable, the garage and the coachman's house 



A Study of the plan presented on this page will show how 

 completely this point has been studied, and also the posi- 

 tion of the house and Its relation to the other buildings on 

 the property, together with the arrangement of the neces- 

 sary roadways of approach, and the garden which form 



service part of the house late in the a;fternoon. 



This is an ideal way to lay-out an interior arrangement 

 of rooms, and the architect has takeij advantage of the 

 possibilities of the site, from which a'successful result has 

 been attained. y . }t ■... . 



A New Sense Organ of Butterflies 



'VERY butterfly collector has had the un- 

 pleasant experience that some butterflies, 

 and particularly those of the species of 

 Catocala (mourning cloak) will notice 

 his approach from a distance and fly away 

 in time. This observation led Tetens to 

 think that these animals must have an 

 auditory organ which warns them of approaching danger 

 by receiving sounds; and accordingly he expressed the sup- 

 position that two pit-like depressions at the first posterior 

 segment of the body might be organs of hearing. 



It is rather surprising that with a group so frequently 

 collected as the Noctuidae, an organ could escape observation 

 which is found quite generally in this group, without diffi- 

 culty with the naked eye as a striking formation on each side 

 of the first abdominal segment. This location probably ex- 

 plains why this organ should have been seen by many per- 

 sons without arousing the suspicion that it could be a sense 

 organ; for naturally enough such organs are looked for 



chiefly at the head, particularly at the feelers, although other 

 parts of the body may be the seat of specific sense organs. 



When examining the animal we see on each side at the 

 line separating the chest from the abdomen and near the 

 points where the rear wings are attached, a deep chan- 

 nel which toward the surface is surrounded by several 

 humps. ■' 



The external morphology of this organ varies in details 

 with the different species of Noctuidae ; vvith some, the open- 

 ing is scarcely visible from the outside, being concealed by 

 long hairs set close together. The microscopic examina- 

 tion shows that only one of the ridges in the vicinity of 

 the cavity of the organ, the one nearest the back, 

 can be considered a "sensitpry ridge,'-' but that this one has 

 true sensltory cells and sensitory hairs-rand thus gives the 

 organ the character of a sense organ. 'Tetens's supposition, 

 mentioned above, that this is an auditory organ, may very 

 well be maintained, since the structure of the organ answers 

 all the requirements of an organ of hearing.
