upon and buckling either end of the strap which passes over the saddle. (2.) The combination and arrangement of straps and buckles (or their equivalent bands of webbing straps and buckles) and a ring described and illustrated in Fig. 2 of the drawings, that is to say, two straps and buckles and a ring so arranged relatively to each other and to the saddle and and its straps or tabs as to constitute a combined girth and surcingle, which can be readily tightened as required by pulling upon and buckling the free end of the strap which passes over the saddle. (3.) The combination and arrangement of straps and buckles (or their equivalent bands of webbing straps and buckles) and a ring described and illustrated in Fig. 3 of the drawings, that is to say, three straps and buckles and a ring so arranged relatively to each other and to the saddle and its straps or tabs as to constitute a combined girth and surcingle, which can be readily tightened as required by pulling upon and buckling either end of the strap which passes over the saddle. (4.) The combination and arrangement of straps and buckles (or their equivalent bands of webbing straps and buckles) described and illustrated in Figs. 4 and 5 of the drawings, that is to say, two straps and buckles, one end of each of which is buckled to one of the saddle straps or tabs, the free end of the first strap passing through a slit in the second strap (or through a ring attached thereto), and thence over the saddle to a buckle on the outer end of the second strap, the said straps and buckles being so arranged relatively to each other and to the saddle and its straps or tabs as to constitute a combined girth and surcingle, which can be readily tightened as required by pulling upon and buckling the free end of the first strap.

No. 15035.—24th June, 1902.—CHARLES DAHL, of Palmerston North, New Zealand, Importer and Manufacturer (assignee of George Shailer, of Palmerston North aforesaid, Settler). An improved butter-mould.

Extract from Specification.—The object of my invention is to provide a cheap and handy machine for the purpose of turning out in one act as nearly as practicable butter when manufactured into the shape or form and of the weight desired. For such purpose I use a mould the body of which is made in two parts intended to act as scoops. These scoops are in form both alike, with this variation: that one of them is open at both ends, while the other has a fixed bottom or side attached to the near end thereof, and is open at the other end only. The interior of these scoops (which is intended to hold and convert the butter into shape) may be of any shape in ordinary use, but for preference and descriptive purposes is herein referred to as of rectangular form, and is expressly designed so as to hold and measure the quantity of butter required. In order to connect the scoops with each other a hinge is attached to the under side of the off and open ends of each scoop, and for the purpose of opening and closing the said scoops by means of such attachment a handle is affixed to the upper side and near end of each scoop. While not limiting myself to the use of any particular metal or substance in the construction of the said mould, for preference I use wood for the whole of the said mould except the hinge, which I make of iron.

Claim.—In moulds for shaping and measuring butter in one act, an improved combination of parts constructed and attached substantially as above described.

No. 15052.—25th June, 1902.—CHARLES COWAN KIDD, of Spring Hills, Southland, New Zealand, Farmer. Improvements in ditch-ploughs.

Extract from Specification.—In this invention there are two beams C, the front ends of which are supported by a sledge or wheels such as E, which may be pivoted so as to turn corners. Each beam is connected at the rear end to blades I, I, hereinafter described. Said beams C are stayed to a frame A by two rods D, which work in loose eyes at each end so as to be self-adjusting as the beams C are raised or lowered. The frame A is mounted on sledges or wheels such as H, as shown in Fig. 3, and is provided with suitable lowering and raising gear such as B for regulating the depth of the blades and consequently the depth of the drain. The blades I, I, are secured to beams C by means of pins or bolts passing through holes S in said beams, and have serrated teeth J, J, which are so shaped that the upper teeth are in advance of the lower ones, which recede in steps, so that when the machine is in operation the top teeth cut the ground ahead of the lower ones, thus easing the ground above and making the cutting-work of the lower ones easier than if the blades were all in line. The two blades I, I, taper slightly downwards towards each other, thus making draught easier, and helping to raise the cut sods upwards. Socks K are placed between the blades I, I, at the long point of each serrated tooth and cut horizontally, decreasing the size and weight of the sods, and make it more easy to remove them from the ditch. An elevator O, Q, is attached to the back of the bottom sock, its two halves O and Q being hinged at P as shown to enable it to be easily used rounding corners. The front of the elevator is pointed, and it gradually rises backwards until it is sufficiently high to throw the sods clear of the ditch when the machine is in operation, as in Fig. 1. One or two mouldboards R help to throw off the sods. When
