Oh, hey!! I remember these cartoons! I've got a few of the DVDs myself (not to mention the inaugural Happy Hour, "Stuff That Flies" on 16mm) and can definitely concur - these really are are hidden gems of the Golden Age, and the humor is indeed very reminiscent of the best of Warners. If you haven't seen 'em, definitely give them a look if you haven't. The DVDs are easily found on Matograph's own online shop for a very affordable price.
In addition to the two cartoons Derek brought up, I have a special fondness for
Every Witch Way and
Yeggs Over Medium, released in 1936 and 1945 respectively. In the former, Hopper and Squint, lost in the the woods, come across a witch's house, unaware that the lady of the house needs the foot of a hare and the tail of a mole in her latest brew, while in the latter, Squint drags his lagomorph chum into the booth of the all-knowing Swami River, whose predictions for the two (which Hopper initially dismisses as a load of hooey) come true in ways that our heroes would have never expected.
These two are especially special to me because the writer of these two shorts, a Mr. Harry Allen was a distant relative of mine, as I found out on one of those genealogy sites some years ago. Imagine my thrill when I found out that this young animation geek had a flesh-and-blood cartoon veteran as a great-uncle! And my research after this discovery sort of led me deep into the Matograph rabbit hole (pun definitely not intended!), and suffice to say, I've been hooked ever since. He also wrote the first of the "Dizzy Dog" cartoons, the other big Matograph star, whose cartoons are also a scream. Helps that I'm a big fan of the antics of the Three Stooges, so a canine with the voice of Curly is an utter joy for me to watch.
