I place at the bottom of some glass tubes, to enable me to make certain observations which I have in mind, a pinch of backward eggs taken from my collection; and on the top I heap lightly a layer of very fine, damp sand. The receptacle is closed with a plug of wet cotton, which will maintain a constant moisture in the interior. The column of sand measures about an inch, which is very much the depth at which the ovipositor places the eggs. Any one seeing my preparations and unacquainted with their object would hardly suspect them of being incubators; he would be more likely to think them the apparatus of a botanist who was experimenting with seeds. My anticipation was correct. Favoured by the high temperature of the summer solstice, the Grasshopper seed does not take long to sprout. The eggs swell; the front end of each is spotted with two dark dots, the rudiments of the eyes. It is quite evident that the bursting of the shell is near at hand. I spend a fortnight in keeping a tedious watch at every hour of the day: I have to surprise the young Decticus actually leaving the egg, if I want to solve a question that has long been vexing my mind. The question is this: the Grasshopper’s egg is buried at a varying depth, according to the length of the ovipositor or dibble. An inch is about the most for the seeds of the best-equipped insects in our parts. Now the newborn Decticus, hopping awkwardly in the grass at the approach of summer, is, like the adult, endowed with a pair of very long tentacles, vying with hairs for slenderness; he carries behind him two extraordinary legs, two enormous hinged levers, a pair of jumping-stilts that would be very inconvenient for ordinary walking. How does the feeble little creature set to work, with this cumbrous luggage, to emerge from the earth? By what artifice does it manage to clear a passage through the rough soil? With its antennary plumes, which an atom of sand can break, with its immense shanks, which the least effort is enough to disjoint, the mite is obviously incapable of reaching the surface and freeing itself. The miner going underground puts on a protective dress. The little Grasshopper also, making a hole in the earth in the opposite direction, must don an overall for emerging from the earth; he must possess a simpler, more compact transition-form, which enables him to come out through the sand, a delivery-shape analogous to that which the Cicada and the Praying Mantis use at the moment of issuing, one from his twig, the other from the labyrinth of his nest.
