mode of protection. In these cases, liowever, they are accompanied by 

 an unpleasant smell and taste, so that the gorgeous dress which would 

 seem so dangerous is in fact a most effectual shield. 



The lecturer pointed out that there were five principal types of 

 coloring among caterpillars. Those which live inside wood or leaves 

 or underground are generally of a pale uniform hue ; the small leaf- 

 eating caterpillars are green, like the leaves on which they feed. The 

 other three types may "siparva licet componere magnis" be compared 

 with the three types of coloring among cats; there are the ground cats, 

 as the lion and puma, which are brownish or sand color, like the open 

 places they frequent; so also, caterpillars which conceal themselves by 

 day at the roots of their plant food, even if originally green, tend to 

 assume the color of earth. The spotted or eyed cats, such as the 

 leopard, live among trees, and their peculiar color renders them incon- 

 spicuous,' by mimicking the spots of light and shade among the foliage. 

 Lastly, there are the striped cats, as the" tiger, which inhabit the jungle, 

 whose markings render them difficult to see among the brown grass 

 they frequent. The stripes of the tiger are transverse because he walks 

 horizontally on the ground ; while the stripes on the caterpillar are 

 either longitudinal or oblique, the direction of the lines follows those 

 of the foliage ; those caterpillars which cling to the grass in a vertical 

 position have longitudinal lines, while those which live on mere leaves 

 have oblique lines, corresponding with the oblique midribs of the leaves. 



THE BLACKBEEEY. 



This fruit has received the least attention at the hands of fruit 

 growers of any of our small fruits. Plants are seldom inquired for, 

 and only a few hundreds are planted, where thousands of currants, 

 raspberries, and gooseberries, and millions of strawberries are set out. 

 Mr. Parry, of New Jersey, is an extensive cultivator of small fruits, 

 and for many years boasted a large number of acres of blackberries 

 under cultivation, and may therefore be considered good authority on 

 the cultivation of this fruit. In a paper read before the Pennsylvania 

 Fruit Growers' Society, at its meeting in January, 1877, he states that 

 tl^is fruit has sold readily in his markets at from twelve and a half to 

 fift-een cents per quart. The average received by him during the past
