These should have roses pierced with very fine holes; the diameter of those usually used is too large. Long-spouted watering pots are required for watering plants in pots upon shelves. French watering pots have zigzag bends in the spout to break from the plant the force of the water. Shelf watering pots are small and flat-bodied for giving water to plants overhead, and near the glass in green-houses or stoves.

"The accompanying engraving is of a watering pot from Mr. G. Thompson, 390 Oxford Street, who states that its superiority consists in the roses being so formed as to give the water thrown from them the nearest resemblance to a gentle shower of rain, which renders it peculiarly suitable for watering seedlings or other tender plants. As the brass joints which connect the roses to the spout are made water-tight, there is no danger of its returning outside, to the annoyance of the person using it: a is the spout to which the roses are screwed; b, the box to contain either spout out of use; c and d, the holes in which the joints are placed; e, a large rose for watering flower beds; /, a smaller rose for watering plants in pots." - Gard. Chron.

Another watering pot is the following, and suggested by Mr. Williamson.

"No. 1 represents the original, which differs from a common watering pot in having its tube inserted in a horizontal position, with a brass valve near the point, through which passes a brass wire or rod, held in its proper position by two strong transverse pieces of wire, perforated in the centre, and connected with a crank or lever, between the lower part of which and the side of the pot is a steel spring, which propels the piston and shuts the valve. From the top of the lever 18 fixed a brass rod, which is kept in its place by a collar brazed to the side of the pot. In raising, the rod is pressed by the finger. No. 2 represents the improvements, which consist in a double lever, acting like the key of a flute. Instead of the steel spring at the end of the lever, a spiral one of brass wire is fixed within the point of the tube, immediately before the valve, which it shuts; at the other end of the tube is a convex rose of copper, to prevent dirt, etc, passing into the tube, through the centre of which passes the rod in connexion with the lever and the valve. No. 3 differs from the preceding only in having a movable curved tube attached to the pipe, at the top of which is a very fine rose about an inch in diameter.

From the length of tube (about twenty inches) the pressure of water is considerable, when the pot is held in an inclined position, producing a light shower admirably suited to small seeds." - Gard. Chron.

A third invention is Mr. Saul's, and, he says, "it can be constructed at a very little more expense than those in general use. In the annexed sketch, Fig. 1 represents a section of the can; 1 1 are removeable tubes, having roses on their upper ends, while the lower ends slide over the tube 2, fixed into the can; 3 is a valve placed over this tube, made of strong leather, and having a small block of wood on the top like those in common pumps, the bottom of the can being wood, the valve is screwed on it, as shown at 4, in such a manner as to be easily taken off, when it requires to be repaired. The rod 5 is connected with the valve 3, and the spring 6; when used, the can may be held by the handle, either in the right hand or the left: by drawing up the spring 6 with the forefinger, the valve is raised by means of the connecting rod 5, and consequently the water flows into the tubes 1 and 2; as soon as the finger is removed from the spring, the valve falls, and the water is stopped. The spring is fixed on the under side of the handle, and nearly all inclosed in that part made to fit the hand.

Fig 2 represents the bottom of the can; the dotted line showing the size of the valve; 1 shows the point at which the water flows into the tubes." - Gard. Chron.
