"In reference to the plan offered by Henry Bushelson, which proposes to run the boats by means of his patent propeller, we may remark that the steam-engine with which the propeller is moved would sink the boat; and even if it would not, the propeller-blades, being longer than the depth of the canal, would dig about five hundred cubic feet of mud out of the bottom at each revolution. As a mud-dredge Bushelson's patent might be a success, but as a motive-power it is a failure; and his suggestion that the tow-path might be cut into lengths and laid side by side and sold for a farm, therefore, is not wholly practicable.
"The idea of William Bradley is that holes might be cut in the bottom of the boat, and through these the legs of the mule could be inserted, so that it could walk along the bottom, while its body is safe and dry inside. This notion is the offspring of a fruitful and ingenious intellect; and if the water could be kept from coming through the holes, it might be considered valuable but for one thing—somebody would have to invent a new kind of mule with legs about seven feet long. Mr. Bradley's mind has not yet devised any method of procuring such a mule, and unless he can induce the ordinary kind to walk upon stilts, we fear that the obstacles to success in this direction may be regarded as insurmountable.
"Mr. Peterman Bostwick urges that important results might be secured by making the canal an inclined plane, so that when a boat is placed upon it the boat will simply slide down hill by the power of the attraction of gravitation. This seems to us a beautiful method of adapting to the wants of man one of the most remarkable of the laws of Nature, and we should be inclined to give Mr. Bostwick the first prize but for the fact that we have discovered, upon investigation, that the water in the canal also would slide down hill, and that it would require about fifteen rivers the size of the Mississippi to keep up the supply. Mr. Bostwick does not mention where we are to get those rivers. He does, however, say that if it shall be deemed inadvisable to slope the canal, the boats themselves might be made in the shape of inclined planes, so that they would run down hill upon a level canal. There is something so deep, so amazing, in this proposition that your committee needs more time to consider it and brood over it.
"Mr. W.P. Robbins proposes to draw off the water from the canal, lay rails on the bottom, and then put the boats on wheels and run them with a locomotive. Your committee has been very much struck with this proposition, but has concluded, upon reflection, that it is rather too revolutionary. If canal navigation should be begun in this manner, probably we should soon have the railroad companies running their trains on water by means of sails, and stage lines traveling in the air with balloons. Such things would unsettle the foundations of society and induce anarchy and chaos. A canal that has no water is a licentious and incendiary canal; and it is equally improper and equally repugnant to all conservative persons when, as Mr. Robbins suggests, the boats are floated in tanks and the tanks are run on rails.
"Your committee has given much thought and patient examination to the plan of Mr. Thompson McGlue. He suggests that the mules shall be clad in submarine armor and made to walk under water along the bottom of the canal, being fed with air through a pump. As we have never seen a mule in action while decorated with submarine armor, we are unable to say with positiveness what his conduct would be under such circumstances. But the objections to the plan are of a formidable character. The mule would, of course, be wholly excluded from every opportunity to view the scenery upon the route, and we fear that this would have a tendency to discourage him. Being under water, too, he might be tempted to stop frequently for the purpose of nibbling at the catfish encountered by him, and this would distract his attention from his work. Somebody would have to dive whenever he got his hind leg over the tow-line; and when the water was muddy, he might lose his way and either pull the boat in the wrong direction or be continually butting against the bank.
"Of the various other plans submitted, your committee have to say that A.R. Mackey's proposition to run the boat by sails, and to fill the sails with wind by means of a steam blower on the vessel; James Thompson's plan of giving the captain and crew small scows to put on their feet, so that they could stand overboard and push behind; William Black's theory that motion could be obtained by employing trained sturgeon to haul the boat; and Martin Stotesbury's plea that propulsion could be given by placing a cannon upon the poop-deck and firing it over the stern, so that the recoil would shove the boat along,—are wonderful evidences of what the human mind can do when it exerts itself, but they are not as useful as they are marvelous."
The prize has not yet been awarded. It is thought that the canal company will have to make it larger before they secure exactly what they want.

There is nothing in common between canals and sausages, but the mention of Mr. William Bradley's name in the above report recalls another report in which it figured. Bradley is an inventor who has a very prolific mind, which, however, rarely produces anything that anybody wants. One of Mr. Bradley's inventions during the war was entitled by him "The Patent Imperishable Army Sausage." His idea was to simplify the movements of troops by doing away with heavy provision-trains and to furnish soldiers with nutritious food in a condensed form. The sausage was made on strictly scientific principles. It contained peas and beef, and salt and pepper, and starch and gum-arabic, and it was stuffed in the skins by a machine which exhausted the air, so that it would be air-tight. Bradley said that his sausage would keep in any climate. You might lay it on the equator and let the tropical sun scorch it, and it would remain as sweet and fresh as ever; and Bradley said that there was more flesh-and-muscle-producing material in a cubic inch of the sausage than in an entire dinner of roast turkey and other such foolery.
So when Bradley had made up a lot of the Imperishable, he stored the bulk of them in the garret; and putting a sample of them in his pocket, he went down to Washington to see the Secretary of War, to get him to introduce them to the army.
