period of three days, once, when Tom-Tom did not leave the cabin, and I did not go out either, as I thought it safer to remain. There was no telling what might happen in my absence. At the end of the third day, I sat at my little table, recording various valuable observations in my ledger, when suddenly a terrible thought struck me. I had forgotten to feed Little Upsidaisi! I dared not make any attempt at it while Tom-Tom was watching me, and though I tried more than once, I could not decoy him out of the cabin. I wondered what had become of my little pet, and feared to find him stretched out stark and stiff upon the returned manuscripts. My heart reproached me bitterly.

A desperate expedient possessed me. After tapping out a few words for Upsidaisi’s comfort, I made a low Kitten cry, such as used to perplex my teacher in my younger days. With every sense instantly alert, Tom-Tom erected his tail and started off down the trail like a blue streak. I supplied the exhausted Mouse with food and drink, and bade him be patient until the following day, using the form of speech which he so readily understood. Tom-Tom soon returned with the air of
