The Reverand John Russel wrote his memouirs and published in 1883. In it he took time to describe his very first Terrier.

Here are a couple of extracts from :

When Jack met Trump...

It was a glorious afternoon towards the end of May, when strolling round Magdalen meadow with Horace in hand, but Beckford in his head, he emerged from the classic shade of Addison's walk, crossed the Cherwell in a punt, and passed over in the direction of Marston, hoping to devote an hour or two to study in the quiet meads of that hamlet, near the charming slopes of Elsfield, or in the deeper and more secluded haunts of Shotover Wood.

But before he reached Marston a milkman met him with a terrier – such an animal as Russell had as yet only seen in his dreams; he halted, as Act?on might have done when he caught sight of Diana disporting in her bath; but, unlike that ill-fated hunter, he never budged from the spot till he had won the prize and secured it for his own.

All about Trump

She was called Trump, and became the progenitress of that famous race of terriers which, from that day to the present, have been associated with Russell's name at home and abroad – his able and keen coadjutors in the hunting-field.

An oil painting of Trump is still in existence, and is, I believe, possessed by H.R.H., the Prince of Wales; but as a copy, executed by a fair and talented artist is now in my possession, and was acknowledged by Russell to be not only an admirabel likeness of the original, but equally good as a type of the race in general, I will try, however imperfectly, to descirbe the portrait as it now lies before me.

In the first place, the colour is white with just a patch of dark tan over each eye and ear, while a similar dot, not larger than a penny piece, marks the root of the tail. The coast which is thick, close, and a trifle wiry, is well calculated to protect the body from wet and cold, but has no affinitiy with the long, rough jacket of a Scotch terrier. The legs are straight as arrows, the feet perfect; the loins and confirmation of the whole frame indicative of hardihood and endurance; while the size and height of the animal may be compared to that of a full-grown vixen fox.
