If we refer to the early history of the Israelitish nation, as told in 1 Sam. iv.-vi., we shall find that the Israelites made an unwarrantable use of the ark, by taking it into battle, and that it was captured and carried off into the country of the Philistines. Then various signs were sent to warn the captors to send the ark back to its rightful possessors. Dagon, their great god, was prostrated before it, painful diseases attacked them, so that many died, and scarcely any seem to have escaped, while their harvests were ravaged by numbers of "mice that marred the land." [Illustration: MOUSE AND NEST.] The question is now simple enough. If the ordinary translation is accepted, and the word Akbar rendered as Mouse, would the necessary conditions be fulfilled, _i.e._ would the creature be destructive, and would it exist in very great numbers? Now we shall find that both these conditions are fulfilled by the common Field-mouse. This little creature is, in proportion to its size, one of the most destructive animals in the world. Let its numbers be increased from any cause whatever, and it will most effectually "mar the land." It will devour every cereal that is sown, and kill almost any sapling that is planted. It does not even wait for the corn to spring up, but will burrow beneath the surface, and dig out the seed before it has had time to sprout. In the early part of the year, it will eat the green blade as soon as it springs out of the ground, and is an adept at climbing the stalks of corn, and plundering the ripe ears in the autumn. [Illustration: JERBOA, OR LEAPING MOUSE.] When stacked or laid up in barns, the harvest is by no means safe, for the Mice will penetrate into any ordinary barn, and find their way into any carelessly-built stack, from which they can scarcely be ejected. The rat itself is not so dire a foe to the farmer, as the less obtrusive, but equally mischievous Field-mouse. The ferret will drive the rats out of their holes, and if they have taken possession of a wheat-stack they can be ejected by depriving them of access to water. But the burrows of the Field-mouse are so small that a ferret cannot make its way through them, and the nightly dew that falls on the stack affords an ample supply of water.
