However, when his idol had fallen, he reverted to the game of reading and writing. He had missed a good deal, so Elizabeth undertook to coach him up to Plaxy's standard. Of course his handlessness made it impossible for him ever to write save with some special apparatus. It was also discovered that, apart from his obvious disability for writing, his reading also was doomed to be very seriously hampered, so crude was his perception of visual form. Plaxy used to spell out simple words with her box of letters, but Sirius found it very difficult to distinguish between C, G, D, O and Q, and also between B, P, R, and K. He was also greatly confused by B and F, by S and Z, by A and H, by H and K. At a later stage, when Plaxy was mastering the lower-case letters, and these in small type, Sirius was still more handicapped. Sometimes it almost seemed that his intelligence was after all sub-human. Elizabeth, who, in spite of her triumphant impartiality towards her child and her foster-child, had always a secret desire for Plaxy to excel, now wrote to Thomas that after all Sirius was not much better than a moron. But Thomas, whose secret desire was the reverse of his wife's, replied with a dissertation on the poor vision of dogs, and urged her to encourage Sirius by telling him of this canine disability, to praise his enterprise in learning to read and write at all, and to remind him that he had great advantages over human beings in other spheres. Encouragement tapped a surprising fund of doggedness in Sirius, for he spent hours every day by himself practising reading. Great progress was made, but after a week or so Elizabeth felt bound to intervene because of symptoms of mental breakdown, She praised him and petted him, and persuaded him that he would leant more quickly and permanently if he tried a hit less hard.

Sirius recognized, of course, that in writing he could not possibly reach Plaxy's standard, but he was determined not to be entirely without this valuable art. It was he himself that invented a way out of his disability. He persuaded Elizabeth to make him a tight leather mitten for his right paw. On the back of the mitten was a socket into which a pen or pencil could be inserted. When this article was completed, he made his first experiment in writing. He was very excited. Lying in the "couchant" position with his left foreleg on the paper to hold it in place, he kept his right elbow on the ground, and was able to scrawl out DOG, CAT, PLAXY, SIRIUS, and so on. The neural organization of his leg and the motor-centres of his brain were probably not at all well adapted to this activity; but once more his doggedness triumphed. Long practice brought him after some years the skill to write a letter in large, irregular but legible characters. In later life, as I shall tell, he even ventured on the task of writing books.

Thomas was more impressed than Elizabeth by Sirius's achievement, because he probably appreciated more fully the difficulties that the puppy had overcome.

So far as possible, Sirius took part in all the simple lessons that Elizabeth gave to Plaxy. He was never very good at arithmetic, perhaps because of his poor visual powers; but he managed to avoid being outclassed by Plaxy, who was none too good herself. His spelling, too, was very bad, probably for the same reason. But at an early age he showed a great interest in language and the art of precise expression. Poetry had sometimes a deep effect on him. In spite of his visual weakness he read a good deal, and he often begged members of the family to read aloud to him. This they did very frequently, knowing how great a boon it was for him.

But to return to his puppyhood. There came a time when it seemed desirable for Plaxy to attend the village school. Sirius, of course, could not do so. It was sometimes with thankfulness for his freedom, but sometimes with envy, that he watched his little foster-sister set off with her books in the morning.
