 ALLOTMENT GARDENS. A system of assigning 



small portions of land to be cultivated by labourers after 



their ordinary day's work. 



The following are the most important rules to be carried 



out ; but, should occasion arise, other rules must be made 



to meet particular cases : 



1. Each Allotment should consist of a rood of land 

 (=i acre) to be let yearly at a rent of not more than 10s. 



2. The Allotment to be let for one year only, to be re-let 

 to the same occupier, provided his character has beeu satis- 

 factory during the preceding year. 



3. The rent shall be considered due at Michaelmas. If it 

 remains unpaid for one month after that date, the Allot- 

 ment shall be forfeited. 



4. The Allotment to be cultivated solely by spade hus- 

 bandry, and the same crop shall not be planted on the 

 same part two years in succession. 



5. Separate Allotments shall be divided by a space not 

 less than 18in. 



6. Any occupier trespassing on his neighbour's Allotment, 

 or in anyway interfering or damaging the same, shall not be 

 allowed to hold his Allotment after the expiration of the year.

 Brazilian, who was of great assistance to St. Hilaire while 

 travelling in Brazil). ORD. Rutacece. Stove trees or shrubs 

 with alternate, simple, entire, stalked leaves. Eacemes 

 terminal, divided at the apex into compound thyrse-like 

 panicles. The undermentioned species will grow freely 

 in a mixture of loam, sand, and peat. Partly ripened

ALNUS (from al, near, and Ian, the bank of a river ; 

 general habitat of the genus). The Alder Tree. ORD. 

 BetnlaceoB. A genus of deciduous trees and shrubs. 

 Flowers monoecious ; barren ones in long drooping au- 

 tumnal catkins, lasting through the winter ; fertile 

 ones, produced in spring, in oval catkins, resembling 

 a fir-cone in shape, the fleshy scales of which beconie 

 indurated and ligneous as they approach maturity.' 

 Leaves stalked, roundish, blunt. Propagated usually by 

 seeds, which are gathered towards the end of October ; they 

 require to be well dried, in order that the cones do not 

 become mouldy. The seeds are sprinkled lightly on the 

 ground with the slightest possible covering. Towards the 

 end of the year, the seedlings will be about lOin. high. 

 They are then planted in rows lft. apart, and 6in. from 

 each other, where they may remain for two years, after 

 which they can be placed out in the situations where they 

 are intended to stand. Planting is best done in November 

 or March ; and, if it is designed to make a plantation of
