is connected to the plough in a novel manner : — by passing a 
chain over the top of the beam, and under the arched axle to the 
end of the draw-bar where the two ends of the chain are con- 
nected, a frictional contact between the beam and the bearer is 
produced immediately the horses begin to draw ; the more or 
less rigid impact, thus set up, firmly secures the beam to the fore- 
carriage as effectively as though they were riveted together, 
the result being that the plough will go without being held. 
The necessary pitch or inclination of the share is obtained or 
varied by a top screw and slot in the plough body. The 
improvements claimed in the " Howard Arc-axle Plough " are 
simplicity in construction, great strength combined with little 
weight, also clearance for ploughing-in manure or surface 
vegetation. The arched axle and the inclination of the furrow- 
wheel give plenty of clearance underneath ; and the cutting or 
coulter edge being on the right or furrow side of the beam, 
nothing lifted by the share and mould-board can choke the 
throat of the plough. The line of draught is got by curving 
the beam to the required point, the ordinary plough-hake being 
replaced by a bow on which the draught-bar slides, to regulate 
the line of draught according to the width of furrow. The 
whole of the wearing parts of the plough — mould-board, landside 
plate, share with reversible point, and new reversible shin-piece 
or cutting edge on the landside which answers the purpose of 
the usual knife-coulter — are all made of chilled-iron, and are con- 
sequently very durable. The beam is of X"Section, and, like the 
body, is of wrought steel. The fore-carriage, dispensing with 
the customary standards, beam-slides, loop-screws, and clips, is 
free from all liability to damage by rough usage, or wearing 
loose. 
This plough we had tried, and the work done was excellent, 
the furrow, 7 b}' 13, leaving the work in the most satisfactory 
manner, perfectly disintegrated and level, with evident ease to 
the pair of horses, which, according to the width of the furrow, 
could plough two acres per day. It was also tried as a skim- 
plough with equally satisfactory results. The price (3/. 15s.) 
appeared moderate.

This invention, patented by Mr. Nathaniel Rix, of Colney, 
St. Albans, relates to improved means for automatically and 
continuously lubricating spindles or axles, or similar rotating 
parts of machinery, and consists in providing a bearing con- 
structed (as is described) with a recess or chamber (one or 
more) for containing the lubricating material, in combination 
with a rotating ring, collar, or lifter (one or more), arranged 
upon the axle, spindle, or shaft, in such a manner as to enter
